Question

Carly works at a local bakery. She needs 6 cups of flour to make a cake and 3 cups of flour to make 16 cupcakes. If she started the day with 20 pounds of flour, and one pound of flour equals four cups of flour, how much flour will Carly have left after she makes 2 cakes and 16 cupcakes?

Answer 1

2 cakes require 10 cups of flour.

16 cupcakes will use 6 cups.

Add up the total to get 16 cups of flour used.

At 4 cups per pound, her 16 used cups of flour weigh 4 lbs. (16/4).

She used 4 lbs from the original 18 lb supply, so when she subtracted that 4 lbs from the 18 lbs she started out with, she discovered she has 14 lbs of flour left to make more goodies!

Hope it correct!!
