To determine the box of cereal with the highest unit price, we need to calculate the unit price for each box. After calculating the unit price for each box, we find that all three boxes have the same unit price of $0.10 per ounce.
The correct answer to the given question is option d.
To determine which box of cereal has the highest unit price, we need to calculate the unit price for each box. The unit price is found by dividing the price of the box by the number of ounces in the box.
Let's calculate the unit price for each box:
A. The 20 ounce box: $2.00 / 20 = $0.10 per ounce
B. The 32 ounce box: $3.20 / 32 = $0.10 per ounce
C. The 48 ounce box: $4.80 / 48 = $0.10 per ounce
All three boxes have the same unit price of $0.10 per ounce, so the correct answer is d) all three boxes have the same unit price.
