Answer 1

D store1 for 0.06

Explanation:

Answer 2

Given:
Store 1 = 36 oz at $26.62
Store 2 = 28 oz at $22.42

To compare which store is cheaper, we need to get the unit cost per ounce.

Store 1: 26.62 / 36 = 0.74 per ounce !CHEAPER!
Store 2: 22.42 / 28 = 0.80 per ounce

Baby formula at Store 1 is cheaper. It is cheaper by 0.06 per ounce from the baby formula sold at Store 2.

Assuming you'll buy 36 oz at store 2.
36 x 0.80 = 28.80 compare with store 1's price 26.62
