At a bakery, the price of a bagel ranges between $0.65 and $1.35 depending on the flavor of the bagel. If a customer purchases 12 bagels of the same flavor, the bakery will provide a 13th bagel free of charge. What is the minimum amount that a customer could pay to receive 13 bagels?

A. $7.25

B. $7.80

C. $8.45

D. $9.10

E. $9.35

In order to pay the minimum possible price for 13 bagels, a customer would want to:

1) Be sure to take advantage of the promotion to get the 13th bagel free.

2) Buy the cheapest possible flavor of bagel.

So here that would mean buying 12 of the $0.65 flavor, and then getting the 13th free. The answer is therefore 12 * 0.65.

You can do this quickly by breaking the calculation into 10 * 0.65 (which is $6.50) plus 2 * 0.65 (which is $1.30) = $7.80. Choice B is correct.
