Question: Michael bought a comic book price at D dollars and C cents and paid with a $10 bill and a $5 bill. The cashier incorrectly charged Michael's C dollars and D cents and returned $2.87 in change. If the cashier had charged Michael the correct price, what would the correct change have been?
Given:
D = dollar = $15 total money
Wrong change = $2.87
Asked: If the cashier had charged Michael the correct price, what would the correct change have been?
Solution:
Wrong change = $2.87
Wrong price = $15 - $2.87 = $12.13
Note: The cashier interchanged the dollar and the cent.
Correct price = $13.12
Correct change = $15 - $13.12 = $1.88
ANSWER: A. $1.88
