A section of books is marked down by 15 percent from an original price of $16 each. How much will it cost to buy three books from the sale section?
Answer
A
$12.60
B
$13.60
C
$37.80
D
$40.80
Explanation
A 15% markdown on each $16 book is $16 × 0.15 = $2.40, so each book costs $16 − $2.40 = $13.60. Three books cost 3 × $13.60 = $40.80, which is choice D.
