Answer:
$24
Step-by-step 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.
