Question

Chris paid $36 for 3 tank tops and 2 T-shirts. A T-shirt cost 3 times as much as a tank top.How much did Chris pay for the 2 T-shirts​

Answer 1

$24

Explanation:

Price of tank-top: x

Quantity of tank-tops: 3

Price of T-shirts: 3x

Quantity of T-shirts: 2

(price of tank top x quantity of tank tops) + (price of T-shirts x quantity of T-shirts) = 36

3x + 2(3x) = 36

3x + 6x = 36

9x = 36

x = 36/9

x = 4

price of 1 T-shirt = 3x = 3(4) = 12

Price of 2 T-shirts = 12 x 2 = $24

Therefore, Chris paid $24 for the 2 T-shirts.
