A Group of 8Th Graders Is Selling T-Shirts and Hats to Raise Money for Their End-Of-Year Party

A Group of 8th graders is selling t-shirts and hats to raise money for their end-of-year party. They earn a profit of $5 per shirt and $10 per hat that they sell.

A. If p stands for the profit that they make, s stands for the number of shirts sold and h stands for the number of hats sold. Write an equation showing the total profit.

B. Find the profit if the students sell:

1. 30 shirts and 50 hats

2. 15 shirts and 10 hats

3. 12 shirts and 20 hats

C. Suppose that the students need to raise $600. Find 5 pairs of shirt and hat sales that would allow them to make exactly $600.

D. 1. Your answer from above can be written as ordered pairs in the form (s, h). Plot those ordered pairs on the grid below.

2. Use the pattern that you see to estimate at least one other solution to the equation 600 = 5s + 10h
