Answer:

B. Brand B, 10 oz. bag for $3.90

Explanation:

The lowest per unit cost of different brands can be calculated using the following formula

Cost per oz=Cost per bag/number of oz in that bag

Brand A Cost per oz=3.60/8=$0.45

Brand B Cost per oz=3.90/10=$0.39

Brand C Cost per oz=6.50/16=$0.406

Brand D Cost per oz=0.59/1=$0.59

So the answer is B. Brand B, 10 oz. bag for $3.90
