At $8 per book, the 8 books SHOULD have cost $64 (8 x $8 = $64)
However, Harry bought the 8 books for $60
So, the amount Harry saved = $64 - $60 = $4

What is savings percentage for Harry, who bought the whole set together?
Percent savings = 100(amount saved)/(original price)
= 100(4)/64
= 100(1)/16
= 100/16
= 25/4
= 6.25%

Answer: B

Cheers,
Brent
