We will demonstrate how to set up the calculation and perform the necessary arithmetic to arrive at the correct answer. By clearly explaining each step, we aim to make the process understandable and reproducible for all readers.

Step 2: Calculation - Cost Per Gallon

Now that we have the conversion factor (1 gallon = 3.785 liters), we can proceed to calculate the cost per gallon of ice cream. The given price is $1.75 per liter. To find the cost per gallon, we need to multiply the price per liter by the number of liters in a gallon. This calculation will effectively convert the price from a per-liter basis to a per-gallon basis. The formula for this conversion is: Cost per gallon = Cost per liter × Liters per gallon. Substituting the given values and the conversion factor, we get: Cost per gallon = $1.75/liter × 3.785 liters/gallon. Performing this multiplication, we have: Cost per gallon = $6.62375. However, since we are dealing with currency, it is standard practice to round the result to the nearest hundredth (two decimal places). Rounding $6.62375 to the nearest hundredth gives us $6.62. Therefore, the cost of ice cream per gallon is approximately $6.62. This result provides a clear and understandable price point for consumers. It allows them to directly compare the cost of ice cream per gallon with other products or other pricing structures. The process of calculating the cost per gallon involves a straightforward application of unit conversion and basic arithmetic. By breaking down the calculation into clear steps, we have demonstrated how to arrive at the solution in a logical and understandable manner. This method can be applied to similar problems involving different units and prices, making it a valuable skill for everyday financial calculations. In the next section, we will discuss the importance of rounding in practical calculations and the implications of different rounding methods. We will also reinforce the significance of accuracy in unit conversions to avoid significant errors in cost assessments.

Step 3: Rounding to the Nearest Hundredth

In the previous step, we calculated the cost per gallon to be $6.62375. However, in practical financial calculations, it is essential to round the result to a reasonable number of decimal places. Typically, when dealing with currency, we round to the nearest hundredth, which represents the cents in a dollar. This rounding ensures that the final answer is presented in a format that is both accurate and easy to understand. Rounding to the nearest hundredth means looking at the digit in the thousandths place (the third decimal place) to determine whether to round up or down. If the digit is 5 or greater, we round up the hundredths place; if it is less than 5, we round down. In our case, the digit in the thousandths place is 3, which is less than 5, so we round down. This means that $6.62375 is rounded to $6.62. The importance of rounding correctly cannot be overstated. Inaccurate rounding can lead to discrepancies in financial calculations, which can have significant consequences in business and personal finance. For example, if we had rounded up to $6.63, even though it was not mathematically correct, it would result in a slightly higher cost per gallon being reported. Over time, these small differences can accumulate and lead to substantial errors. In addition to financial calculations, rounding is a common practice in many areas of mathematics and science. It is a way to simplify numbers and make them easier to work with, while still maintaining a reasonable level of accuracy. The choice of how many decimal places to round to depends on the context and the level of precision required. In this case, rounding to the nearest hundredth is appropriate because it aligns with the standard practice for representing monetary values. The final answer, $6.62 per gallon, provides a clear and practical understanding of the cost of ice cream when priced at $1.75 per liter.
