Answer :
Final answer:
To find the amount of cinnamon needed for 60 cookies, a proportion is used based on the original recipe requirements. By setting up a ratio and solving for the unknown quantity, it is determined that 3 3/4 teaspoons of cinnamon are required.
Explanation:
The question is asking us to scale the amount of cinnamon needed for a different number of oatmeal cookies. The original recipe calls for 1 1/2 teaspoons of cinnamon for 2 dozen (24) cookies. To find out how much cinnamon we need for 60 cookies, we can set up a proportion:
(1 1/2 teaspoons / 24 cookies) = (x teaspoons / 60 cookies)
First, convert 1 1/2 teaspoons to a decimal which is 1.5 teaspoons. Now, cross multiply to solve for x:
1.5 * 60 = 24 * x
90 = 24x
x = 90 / 24
x = 3.75
Therefore, 3 3/4 teaspoons of cinnamon are needed for 60 cookies. The correct answer is C) 3 3/4 teaspoons.
