There are 3 bags of popcorn at the movie theater. Which one is the best buy?

Bag A $4.50 for 10 oz.
Bag B $6.00 for 15 oz.
Bag C $7.50 for 20 oz.
A. Bag A
B. Bag B
C. Bag C
D. Bag A and Bag B are equally good values.

To compare the value of each bag, we need to find the price per ounce of popcorn.

Bag A: $4.50 ÷ 10 oz. = $0.45 per oz.
Bag B: $6.00 ÷ 15 oz. = $0.40 per oz.
Bag C: $7.50 ÷ 20 oz. = $0.38 per oz.

Therefore, Bag C has the best value as it has the lowest price per ounce of popcorn. The answer is C.
