Final answer:
The correct answer is Per unit cost. Per unit cost allows shoppers to make accurate comparisons between item sizes and brands.
Step-by-step explanation:
The correct answer is Per unit cost.
Per unit cost allows shoppers to make accurate comparisons between item sizes and brands by dividing the cost of the item by its quantity or unit size. This allows shoppers to see the cost of each unit or each ounce, for example, and compare it across different brands or sizes.
For example, if a can of soda costs $1.50 and contains 12 ounces, the per unit cost would be $1.50/12 = $0.125 per ounce. By comparing the per unit cost of different soda brands, shoppers can determine which brand offers the best value.
