A and B agree to share the cost of an $18 pizza based on how much each would eat. B ate 3/2 of the pizza that A ate. How much should A and B each pay?

A = pizza eaten by A

3/2 A = pizza eaten by B 

 

A + 3/2 A = 1   whole pizza

5/2 A = 1 

A = 2/5  of the pizza       so:    2/5 * $ 18 = $ 7.20 = A share       and       B  pays the rest = $ 10.80
