Final answer:
To adjust the recipe for 4 dozen cookies, you will need 2.5 cups of vegetable oil, 3 1/3 teaspoons of almond extract, and 4 3/4 cups of oatmeal.
Step-by-step explanation:
To adjust the recipe for 4 dozen cookies, you will need to increase the amount of each ingredient proportionally. The original recipe calls for 1 7/8 cups of vegetable oil, 2 1/2 teaspoons of almond extract, and 3 1/2 cups of oatmeal for 3 dozen cookies. To find the amount of each ingredient for 4 dozen cookies, we can use the ratio:
3 dozen cookies / 1 7/8 cups of oil = 4 dozen cookies / x cups of oil
Cross-multiplying:
3 * x = 4 * 1 7/8
3x = 4 * 15/8 = 60/8 = 7.5
x = 7.5/3 = 2.5
Therefore, you will need 2.5 cups of vegetable oil for 4 dozen cookies. Repeat this process for the other ingredients to find the amount needed. In this case, you will need 3 1/3 teaspoons of almond extract and 4 3/4 cups of oatmeal.
