Please help

We are making chocolate chip cookies for our proportions party! We need to make sure we make enough so that everyone can have 1 cookie, and 200 people will be coming (because who would miss a proportions party, right?). The recipe for 20 cookies calls for 1/4 cup of sugar. How much sugar do we need in order to make 200 cookies?
A. 3/4 cups
B.1 1/4 cups
C.2 1/2 cups
D. 5 cups

Answer 1

Answer: C. 2 1/2 cups

Explanation:

you can set up a proportion based on the recipe for 20 cookies that calls for 1/4 cup of sugar.

Let "S" be the amount of sugar needed for 200 cookies.

The proportion would look like this:

(1/4 cup sugar for 20 cookies) = (S cups sugar for 200 cookies)

Now, you can set up the proportion and solve for S:

(1/4) / 20 = S / 200

To solve for S, first, find the value of (1/4) divided by 20:

(1/4) / 20 = 1 / (4 * 20) = 1 / 80

Now, multiply both sides by 200 to find S:

S = (1/80) * 200 = (1/80) * 200/1 = (1/80) * 200 = 2.5

So, you would need 2.5 cups of sugar to make 200 cookies.

The correct answer is C. 2 1/2 cups.
