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.
This is easy enough to figure out in my head working backwards (Tank top costs $4, t-shirt costs $12, therefore 2 T-shirts costs $24) but I am having a hard time creating the equation and order of operations. Help is greatly appreciated.
