Question

suppose you go to a concert and purchase 3 identical t-shirts and a hat. the hat cost $21 and you spend $60 in all how much does each t-shirt cost ?

Answer 1

if the hat costs 21, and you spent 60, subtract 21 from 60 and you get 39. then divide 39 by how many t-shirts, so 39/3 = 13. so each t-shirt should cost $13

Answer 2

Ok, first you subtract 21 from 60.
That gives you 39, so you then divide that by 3.
That gives you 13, so each t-shirt cost $13.
Hope this helps
