Carly works at a local bakery. She needs 4 cups of flour to make a cake and 4 cups of flour to make 16 cupcakes. If she started the day with 18 pounds of flour, and one pound of flour equals four cups of flour, how much flour will Carly have left after she makes 4 cakes and 48 cupcakes?

x< 5                 x> 3

3< x< 5

f is the midpoint of
