Answer: To find out how much a 5-ounce serving of the frozen Scandinavian vegetable mix costs, we need to calculate the cost per ounce first.
Given that a 2 ¾-pound bag costs $0.88 per pound, we can calculate the cost per pound as follows:
Cost per pound = $0.88
Since there are 16 ounces in a pound, we can calculate the cost per ounce by dividing the cost per pound by 16:
Cost per ounce = Cost per pound / 16
Cost per ounce = $0.88 / 16
Cost per ounce ≈ $0.055
Now, to find the cost of a 5-ounce serving, we can multiply the cost per ounce by 5:
Cost of a 5-ounce serving = Cost per ounce * 5
Cost of a 5-ounce serving ≈ $0.055 * 5
Cost of a 5-ounce serving ≈ $0.275
Therefore, the cost of a 5-ounce serving of the frozen Scandinavian vegetable mix is approximately $0.275, which is closest to option (b) $0.28.
