High School

Will brought a 144-ounce cooler filled with water to soccer practice. He used 16 ounces from the cooler to fill his water bottle. He then took out 16 plastic cups for his teammates and put the same amount of water in each cup.

Find and graph the number of ounces of water, [tex]x[/tex], that Will could have put in each cup. Use the drawing tools to form the correct answer on the provided number line.

Answer :

Each cup could have 8 ounces of water. The graph should represent x = 8 as a point on the number line.

1. Understanding the Problem:

  • Will had 144 ounces of water.
  • He used 16 ounces for his water bottle.
  • The remaining water is 144 - 16 = 128 ounces.
  • He filled 16 plastic cups with equal amounts of water.

2. Setting Up the Equation:

  • Let x be the number of ounces in each cup.

Since he distributed 128 ounces equally among 16 cups, we set up the equation:

128 = 16x

3. Solving for x:

Divide both sides by 16:

x = 128 ÷ 16

x = 8 ounces per cup.

4. Graphing the Solution:

The solution should be plotted at x = 8 on the number line.

Since x represents a specific quantity, it should be marked as a closed point at 8.

This means each cup received 8 ounces of water.

The number line:

The graph represents the number line with a closed dot at x = 8, indicating the solution.

Sure! Let's solve the problem step-by-step.

1. Start with the total amount of water: Will brought a cooler filled with 144 ounces of water.

2. Fill the water bottle: Will used 16 ounces to fill his water bottle. So, we need to subtract this amount from the total water in the cooler.

[tex]\[
\text{Water remaining} = 144 - 16 = 128 \, \text{ounces}
\][/tex]

Now there are 128 ounces of water left in the cooler.

3. Distribute the water into cups: Will took out 16 plastic cups for his teammates and wants to put the same amount of water into each cup.

4. Calculate the amount of water per cup: We divide the remaining water by the number of cups to find out how much water goes into each cup.

[tex]\[
x = \frac{128}{16} = 8 \, \text{ounces per cup}
\][/tex]

So, Will could put 8 ounces of water in each cup.

5. Graph the result on a number line: We would represent this on a number line by marking the value 8, as this is the amount of water in each cup.

In summary, Will can put 8 ounces of water in each of the 16 cups.
