The price per pair of brand A jeans is $45 and the price per pair of brand B jeans is $65. If there is no sales tax and Chris chooses only from among these two brands, what is the greatest number of pairs of jeans that he can buy with exactly $560?
A. 8
B. 10
C. 12
D. 14
E. 20
With $560, he can buy 12 pairs of brand A jeans with $20 left over (notice that 12 x 45 = $540), or he can buy 11 pairs of brand A jeans and 1 pair of brand B jeans with no money left over (notice that 11 x 45 + 65 = $560). Regardless of which option he chooses, the greatest number of pairs of jeans he can buy is 12.
