Answer:
Apple A
Step-by-step explanation:
The first step to solve this problem is to convert all of the weights into pounds. Since 1 lb is equal to 16 oz, the 12 oz weight is equal to 0.75 lb.
The second step is to divide each of the costs by its associated weight.
Apple A: $6.90 ÷ 6 lb = $1.15 per pound
Apple B: $0.90 ÷ 0.75 lb = $ 1.20 per pound
Apple C: $0.45 ÷ 0.25 lb = $1.80 per pound
Comparing these results shows that apple A costs the least per pound.
