Question

Write an equation that could be used to answer the question above. First, choose the appropriate form. Then, fill in the blanks with the numbers 125, 5, and 40. Let x represent the number of t-shirts.

Answer 1

If we assume that we don't need t find the number of hats, then we can say that the profit from -tshirts would be $125 minus 40 or $85

Then we can write the following equation of x is the number of t-shirts:

5x = 85

If we solve by diving both sides of the equation by 5:

5x/5 = 85/5

x = 17 t-shirts sold
