Help pweaseeeeeeeeeeeeeeeeeeeeeeeeeee! One cup of butter is enough for 12 of Kathy's cookies, and one cup of sugar is enough for 8 of her cookies. If she used five more cups of sugar than of butter, how many cookies did she make?

OpenStudy (anonymous):

(2 cups of butter + 3 cups of sugar = 24 cookies)*5 = 10 cups butter + 15 cups sugar = 120 cookies
