Let total cookies=100. (Choose a number divisible by 4 and 5)

# choc chip = x

x = 1/4 of 100 = 25

75 cookies left.

# oatmeal raisin = y

y = 1/5 of 75 = 15

Plug in x = 25, y = 15. Only E gives x = 25.

Shouldn't it be the other way around because 5/3(25) is 5/75 which is 1/15

I should have been more careful with variables. When doing the problem, I used variables labeled "CC" and "OR."

I plugged in the right number (i.e., I plugged in what I got for oatmeal raisin in order to get # of chocolate chip cookies in terms of # of oatmeal raisin cookies) and got the right answer, just mislabeled when posting.

Yes, it should be the other way around: for the numbers I chose, plug in x = 15 and look for answer of 25. Edited. Thanks much!
