Answer:
Stores A, B, C and D
Step-by-step explanation:
Divide the total price by the amount of pounds. For store A: (8.16/4) = $2.04.
For Store B: (6.51/3) = $2.17
For Store C: (2.66/2) = $1.33
For Store D: (11.4/4) = $2.85
All of these prices per unit are less than the current $2.91. Therefore they are all correct.
