Answer 1

part a : 0.65 Part b: 0.60

Explanation:

part a

6.50/10=0.65

part b

3.60/6=0.60

Answer 2

Store A is selling $0.65 per cookie.

`(6.50)/(10)=0.65`

Store B is selling $0.60 per cookie.

`(3.60)/(6) = 0.6`

Store B sells cheaper cookies than store A, so Store B will be the better buy.
