After acquiring toys and books, Nestor had a fraction of his original money left. This remaining fraction provides us with a critical clue in determining Nestor's total initial funds. The magnitude of this remaining fraction reflects the cumulative impact of Nestor's spending decisions on his financial resources. By carefully considering this fraction, we can begin to reverse engineer Nestor's spending journey and determine the total amount of money he initially possessed. The ultimate goal of our mathematical journey is to determine the exact amount Nestor spent on books. This value represents a key piece of information in understanding Nestor's overall spending patterns during May. To achieve this goal, we will meticulously analyze the information provided, applying mathematical principles and logical deduction to arrive at the solution. The amount spent on books is a tangible representation of Nestor's literary pursuits and forms a significant component of his total expenditures. Unlocking this value will provide us with a deeper understanding of Nestor's financial priorities during May.

Unraveling the Puzzle: How Much Did Nestor Initially Have?

To determine the amount Nestor spent on books, we must first ascertain the total amount of money he had initially. This step is crucial because the amount spent on books is calculated as a fraction of the money remaining after the toy purchase. Let's denote the initial amount of money Nestor had as "X". Nestor spent $90 on toys, leaving him with "X - $90". This subtraction represents the reduction in Nestor's funds resulting from his toy purchase. The value of "X - $90" serves as the foundation for subsequent calculations, as it represents the money available to Nestor for book purchases and any remaining funds. Understanding this value is essential for unraveling the puzzle of Nestor's spending habits. After purchasing toys, Nestor allocated 1/4 of the remaining money on books. This fraction is applied to the value of "X - $90", resulting in the amount spent on books. The exact amount spent on books is a key unknown that we are trying to determine. However, by expressing the amount spent on books as a fraction of the remaining money, we establish a mathematical relationship that will help us solve for the unknown. The allocation of 1/4 of the remaining money towards books represents a significant portion of Nestor's spending activities. Following the book purchase, Nestor had 1/3 of his initial money left. This remaining fraction is crucial because it allows us to set up an equation that relates the initial amount of money (X), the amount spent on toys and books, and the final remaining amount. The equation will form the core of our mathematical solution. The remaining 1/3 of his initial money represents the culmination of Nestor's spending decisions. This fraction provides us with a critical benchmark for evaluating the impact of Nestor's expenditures. By comparing this remaining fraction to the initial amount of money, we can gain insights into Nestor's financial planning and allocation strategies. We can express this information in the following equation: (X - $90) - (1/4)(X - $90) = (1/3)X. This equation encapsulates the essence of Nestor's spending journey, connecting his initial funds, toy expenditure, book allocation, and remaining balance. The equation forms the foundation for our mathematical analysis and will allow us to solve for the unknown variable "X". Each component of the equation represents a specific aspect of Nestor's financial activities. The term (X - $90) represents the money remaining after the toy purchase. The term (1/4)(X - $90) represents the amount spent on books. The term (1/3)X represents the final remaining amount. By carefully balancing these components, we can isolate the unknown variable and determine the initial amount of money Nestor possessed. To solve this equation, we first simplify it by combining like terms and isolating the variable "X". This process involves algebraic manipulation and careful attention to mathematical rules. The simplification process is a crucial step in solving for the unknown variable. By systematically simplifying the equation, we can progressively eliminate complexities and reveal the underlying solution. Each algebraic operation performed brings us closer to determining the value of "X", which represents the initial amount of money Nestor had. Multiplying both sides of the equation by 12 (the least common multiple of 3 and 4) to eliminate the fractions, we get: 12(X - $90) - 3(X - $90) = 4X. This multiplication step is a strategic move that eliminates fractions and simplifies the equation. By multiplying both sides by the least common multiple, we create whole number coefficients, making the equation easier to manipulate and solve. The resulting equation is more manageable and allows us to proceed with algebraic simplification without the complications of fractions. Expanding the terms, we have: 12X - $1080 - 3X + $270 = 4X. This expansion step involves distributing the coefficients across the terms within the parentheses. By expanding the terms, we remove the parentheses and create a linear equation with individual terms. The expanded equation is a more transparent representation of the relationships between the variables and constants. This allows us to proceed with combining like terms and isolating the unknown variable. Combining like terms, we get: 9X - $810 = 4X. This step involves grouping terms with the same variable or constant together. By combining like terms, we simplify the equation and reduce the number of individual terms. The resulting equation is a more concise representation of the original relationship. This makes it easier to manipulate and solve for the unknown variable. Subtracting 4X from both sides, we have: 5X - $810 = 0. This subtraction step isolates the variable term on one side of the equation. By subtracting 4X from both sides, we move the variable term to the left side and eliminate it from the right side. The resulting equation is a crucial step in solving for the unknown variable, as it brings us closer to isolating "X" and determining its value. Adding $810 to both sides, we find: 5X = $810. This addition step isolates the variable term further. By adding $810 to both sides, we move the constant term to the right side of the equation. The resulting equation is a significant milestone in the solution process, as it presents the variable term isolated on one side and a numerical value on the other side. Dividing both sides by 5, we determine: X = $162. This division step solves for the unknown variable "X". By dividing both sides by 5, we isolate "X" and determine its numerical value. The value of "X" represents the initial amount of money Nestor had. This is a crucial piece of information that allows us to answer the question of how much Nestor spent on books. Therefore, Nestor initially had $162. This value serves as the foundation for calculating the amount Nestor spent on books.

Calculating the Book Expenditure: Unveiling the Final Amount

Now that we know Nestor initially had $162, we can determine the amount he spent on books. Nestor spent 1/4 of the money remaining after the toy purchase on books. This information is crucial for calculating the exact amount Nestor allocated to his literary pursuits. The fraction 1/4 represents the proportion of the remaining funds that Nestor designated for book purchases. By applying this fraction to the funds remaining after the toy purchase, we can determine the specific amount spent on books. The amount Nestor spent on books is a significant component of his overall spending activities. Understanding this value provides insights into Nestor's financial priorities and his allocation of resources. The remaining money after buying toys was $162 - $90 = $72. This subtraction represents the reduction in Nestor's funds resulting from his toy purchase. The value of $72 serves as the base amount for calculating the amount spent on books. This is because Nestor spent 1/4 of this remaining amount on his literary acquisitions. The calculation of this remaining amount is a critical step in determining the amount spent on books. It establishes the financial context for Nestor's book purchase and provides the necessary information for applying the fractional value. Nestor spent 1/4 of $72 on books. To calculate this amount, we multiply 1/4 by $72. This multiplication represents the application of the fractional value to the remaining funds. The result of this multiplication will reveal the exact amount Nestor spent on books. The multiplication operation is a straightforward mathematical process that translates the fractional proportion into a specific monetary value. By performing this calculation, we can quantify Nestor's investment in books and gain a clearer understanding of his spending habits. (1/4) * $72 = $18. This calculation reveals the amount Nestor spent on books. The result of $18 represents the specific monetary value Nestor allocated to his literary purchases. This value provides a concrete answer to the question of how much Nestor spent on books. The amount of $18 represents a tangible investment in Nestor's education and personal enrichment. It highlights the importance Nestor places on acquiring knowledge and pursuing his intellectual interests. Therefore, Nestor spent $18 on books.
