Question

Greg brought 6 of his button-down shirts to a secondhand store to sell. He was paid the same amount of cash for each shirt. Before he left, Greg spent $27.50 of his earnings on a used suit jacket. He had $17.50 remaining.

Which equation can you use to find the value, s, of each shirt?

Answer 1

Answer: 6s = 45, s = $7.50

Explanation:

We know that Greg had 6 shirts, and that "s" equals 1 shirt. Therefore, on one side of our equation, we want to multiply 6 * s, or 6s.

We also know that Greg used the money he made to buy the suit jacket for $27.50 and then had $17.50 remaining. If we add these 2 numbers, we get the total amount he received for the shirts. This is $27.50 + $17.50 = $45.

Therefore, we know that 6s = 45. If we want to find the amount he was paid for each shirt, we divide both sides by 6 and find that s, or one shirt, is valued at $7.50.
