Honey And Gasoline Puzzle Solving For Empty Container Weight

Figuring out the weight of things can sometimes feel like a real brain-bender, especially when you're dealing with tricky situations like the one we're about to explore. Imagine you've got a container filled with honey, and then you've got the same container filled with gasoline. They weigh different amounts, and you know that gasoline is lighter than honey. The big question? What's the weight of the container all by itself? This isn't just a fun riddle; it's the kind of problem-solving that can come up in all sorts of real-life situations, from cooking to construction. So, let's dive into the challenge and break down how to find the answer step by step.

Unpacking the Problem Weights and Densities

Let's start by making sure we all understand what we know and what we need to figure out. We've got a container. When it's filled with honey, the whole thing weighs 500 grams. When we empty out the honey and fill it with gasoline, it weighs just 350 grams. Now, here's a crucial piece of information gasoline is half as dense as honey. This density difference is key to solving the puzzle. Density, in simple terms, tells us how much 'stuff' is packed into a certain space. Think of it like this a kilogram of feathers takes up way more space than a kilogram of iron. The iron is denser because it packs more mass into a smaller volume. In our case, honey is denser than gasoline, which means that for the same amount of space, honey will weigh more. Understanding this concept is fundamental to cracking the problem. We're not just dealing with weights; we're dealing with how much the substances themselves weigh relative to their volume. We need to use this information to figure out how much of the 500 grams and 350 grams comes from the container itself, and how much comes from the honey or gasoline.

Key Information Breakdown

To solve this problem effectively, we need to clearly break down the information provided. This will help us organize our thoughts and identify the relationships between the different variables. Here's a structured breakdown of the key information:

• Weight of container with honey: 500 grams
• Weight of container with gasoline: 350 grams
• Density relationship: Gasoline is half as dense as honey

Now, let's define some variables to represent the unknowns:

• Let 'C' represent the weight of the empty container (in grams)
• Let 'H' represent the weight of the honey (in grams)
• Let 'G' represent the weight of the gasoline (in grams)

With these variables, we can express the given information as two equations:

1. C + H = 500 (The weight of the container plus the honey equals 500 grams)
2. C + G = 350 (The weight of the container plus the gasoline equals 350 grams)

These equations are a crucial step forward. They translate the word problem into a mathematical form that we can work with. However, we still have three unknowns (C, H, and G) and only two equations. This is where the density information comes into play. The density relationship will provide us with the third piece of information we need to solve for the unknowns. Remember, gasoline being half as dense as honey means that for the same volume, gasoline will weigh half as much as honey. This relationship is the key to unlocking the solution. Before we can use this information effectively, we need to understand how it translates into an equation that involves our variables.

The Density Connection

Now, let's dig deeper into the density relationship. We know that gasoline is half as dense as honey. This is a critical piece of the puzzle, but how do we turn this into a useful equation? Remember, density is about the amount of mass packed into a certain volume. Since the container is filled to the same level whether it's honey or gasoline inside, the volume of the honey and the gasoline is the same. This is a crucial point! If the volume is the same, and gasoline is half as dense as honey, then the weight of the gasoline will be half the weight of the honey. This gives us a direct relationship between H (the weight of the honey) and G (the weight of the gasoline). We can write this relationship as:

G = H / 2

This equation is the missing link! It connects the weight of the gasoline and the weight of the honey, giving us a third equation to work with. Now we have a system of three equations and three unknowns, which means we can solve for C (the weight of the container). Let's recap our equations:

1. C + H = 500
2. C + G = 350
3. G = H / 2

These equations represent the mathematical model of our problem. They capture all the information we have in a concise and usable form. The next step is to use these equations to solve for C. There are several ways to do this, such as substitution or elimination. We'll explore these methods in the next section. The important thing is that we've successfully translated the word problem into a set of mathematical relationships that we can manipulate to find the answer. This process of translating real-world scenarios into mathematical models is a powerful skill that's used in many different fields.

Solving the Equations Substitution Method

With our three equations in hand, we're ready to find the weight of the empty container (C). One of the most common and effective ways to solve a system of equations like this is the substitution method. The idea behind substitution is simple we isolate one variable in one equation and then substitute that expression into another equation. This reduces the number of variables in the second equation, making it easier to solve. Let's see how this works in our case. We have the following equations:

1. C + H = 500
2. C + G = 350
3. G = H / 2

Notice that equation (3) already has G isolated in terms of H. This makes it a perfect candidate for substitution. We can substitute the expression 'H / 2' for G in equation (2):

C + (H / 2) = 350

Now we have an equation that involves C and H only. But we still need to eliminate one more variable to solve for C. We can use equation (1) to do this. Let's isolate H in equation (1):

H = 500 - C

Now we have an expression for H in terms of C. We can substitute this expression into the equation we derived earlier:

C + ((500 - C) / 2) = 350

We've done it! We now have a single equation with only one variable C. This equation can be solved using basic algebra. The next step is to simplify the equation and solve for C. This involves distributing, combining like terms, and isolating C on one side of the equation. Once we've found the value of C, we'll have the weight of the empty container. The power of the substitution method lies in its ability to systematically reduce a complex problem with multiple variables into a simpler problem that can be solved directly. This is a valuable technique in mathematics and many other fields.

Solving for C The Final Steps

Let's continue where we left off and solve for C in the equation:

C + ((500 - C) / 2) = 350

The first step is to get rid of the fraction. We can do this by multiplying both sides of the equation by 2:

2 * [C + ((500 - C) / 2)] = 2 * 350

This simplifies to:

2C + (500 - C) = 700

Now we can combine like terms on the left side:

2C - C + 500 = 700

Which simplifies to:

C + 500 = 700

Finally, to isolate C, we subtract 500 from both sides:

C = 700 - 500

This gives us:

C = 200

So, the weight of the empty container is 200 grams! We've successfully solved the problem using the substitution method. But before we declare victory, it's always a good idea to check our answer. We can do this by plugging C = 200 back into our original equations and seeing if they hold true. This is a crucial step in problem-solving, as it helps us catch any errors we might have made along the way. Let's verify our solution in the next section.

Verifying the Solution Does It Add Up?

We've found that the weight of the empty container (C) is 200 grams. To make sure we haven't made any mistakes, let's plug this value back into our original equations and see if they hold true. Our equations were:

1. C + H = 500
2. C + G = 350
3. G = H / 2

Substituting C = 200 into equation (1):

200 + H = 500

Subtracting 200 from both sides, we get:

H = 300

So, the weight of the honey (H) is 300 grams. Now, let's substitute C = 200 into equation (2):

200 + G = 350

Subtracting 200 from both sides, we get:

G = 150

So, the weight of the gasoline (G) is 150 grams. Finally, let's check if equation (3) holds true:

G = H / 2

Substituting the values we found for G and H:

150 = 300 / 2

This is true! 150 does indeed equal 150. Since our value for C satisfies all three equations, we can be confident that our solution is correct. The weight of the empty container is indeed 200 grams. This verification process is a valuable habit to develop when solving mathematical problems. It not only helps us catch errors but also deepens our understanding of the problem and the relationships between the variables. In the next section, we'll recap the steps we took to solve this problem and discuss some of the key takeaways.
