Question

a book store is having a sale. all hardback books are 20% off l, and all paperbacks are 10% off. suppose you buy four paperbacks that originally costs $9 each and two hardbacks that originally costs $20 each. what percent of the total cost have you saved? round to the nearest percent.

Rarrininger is correct

Answer 2

# of books = 4 ; original cost = 4*9=36; savings = 0.10*36= 3.60

# of books = 2 ;original cost = 2*20=40; savings = 0.20*40= 8.00


Percent savings:
original total cost=$76
Total savings = $11.60
Percent savings: 11.60/76 = 0.1526..= 15.26%
