**CONCEPT: **The question tests on basic application techniques used algebra

**SOLUTION: **

Let Jane sell "a" cookies 96 cents/cookie.

Thus total money earned from cookies = a*96 cents

Let Jane buy "b" popsicles 30 cents/popsicle.

Thus total money spent on popsicles = b*30

As she had no money left over, total money earned from cookies =total money spent on popsicles

=> a*96 = b*30

=> a = (b*30)/96

= b* 5/16

For a to be minimum, use b=16 and we have Minimum a =5

**. (OPTION B)**
