Question

During a sale at a bookstore, a customer buys one book at full price. The customer is given a 25 percent discount on a second book of equal or less value. If George buys two books that value full prices of $17 and $8, by what percent is the total cost of the two books reduced during the sale?

Answer 1

8% First, determine what book the discount is applied to. That will be the lower priced book, so the customer saves 25% of the cost of $8, giving 25% * $8 = 0.25 * $8 = $2 So there's a total savings of $2. Now determine what the total price of purchasing both books without the discount. That would be $17 + $8 = $25 And finally, determine what percent of $25 that $2 is, so $2 / $25 = 0.08 = 8%

Answer 2

Amount paid for the first book is $17.

Amount paid for the second book is 0.75 x 8 = $6

Total amount paid = $17 + $6 = $23

Total full cost of the two books = $17 + $8 = $25

Amount of discount = $25 - $23 = $2

% reduction =
`(2)/(25) *100\%=8\%`

Therefore, the percent of the total cost of the two books reduced during the sale is 8%
