Question

The Robinson family is going to the movies. Each ticket cost $5.50, and there are 5 members of the family. If Mr. Robinson pays with one $20 bill and one $10 bill, how much change should he get back?

Answer 1

The actual cost is

5($5.50) = ?

Mr. Robinson paid

$20 + $10 = ?

Subtract the actual cost from the amount he paid. That is the change he should get.

($20 + $10) - 5($5.50) = ?
