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.
This week, the store has a sale: 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 (2)
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. Hope this helps! ~ ArchimedesEleven
The customer originally bought 12 books last week, spending $13.85. This week, the total cost for the same number of books would be $12.05. Therefore, the customer would save $1.80 by purchasing the books this week.
