Question

A used-book store sells paperback books for $1.30 with a $0.25 discount for each book more than 5 that a customer buys. A customer bought some books last week for $13.85. The store has a sale this week. The price for each book is $1.15, with the same discount on each book over 5 purchased. How much would the customer save if the same books were bought this week?

Answer 1

The customer originally bought 12 books. If this customer still purchases this number:
1.15 x 5 = 5.75
0.90 x 7 = 6.30
5.75 + 6.30 = $12.05
$13.85 - $12.05 = Customer would have saved $1.80.
