Final answer:
The total amount of flour required for the recipe in ounces is calculated by multiplying 3.25 cups (3 1/4 cups converted to a decimal) by 4.5 ounces per cup, which equals 14.625 ounces. However, this calculated total does not match any of the multiple-choice options provided, indicating a possible typo or error.
Step-by-step explanation:
To calculate the total amount of flour in ounces for the recipe, first multiply the number of cups by the ounces per cup. The recipe calls for 3 1/4 cups of flour. Since 1 cup equals 4.5 ounces, convert the fractional cup into a decimal (3 + 1/4 = 3.25 cups) and then perform the multiplication: 3.25 cups × 4.5 ounces/cup = 14.625 ounces. Therefore, the total amount of flour required for the recipe is 14.625 ounces. However, this amount is not an option given in the multiple-choice answers. It appears there may be a typo or error as none of the provided answers match the calculated amount.
