Question

Philip purchased s pairs of shoes for the school year. He also purchased jeans and T-shirts.

The number of pairs of jeans is 3 more than the number of pairs of shoes and the number of
T-shirts is twice as many as the number of pairs of jeans. How many shoes did he purchase if he purchased a total of 17 items?

Answer 1

3 pairs of shoes

Explanation:

You can represent the amount of each item with these:

2(jeans) = t-shirts

shoes + 3 = jeans

shoes + t-shirts + jeans = 17

By plugging in 3 for s, you get:

(3) + 3 = 6

(6) × 2 = 6

3 + 6 + 6 = 17
