Question

There are 4 cups in a pound of flour. A recipe for biscuits calls for 2 3/4 cups of

flour to make a batch of 4 dozen biscuits. Antonio starts with a full 5-pound bag of flour and bakes 16 dozen biscuits. How much flour is left when he is finished baking?
A)5 cups
B)9 cups
C)11 cups
D)17 1/4 cups

Answer 1

Since Antonio makes 4 times the biscuits he uses 4 times the flour.
4 * 2 3/4 = 11 cups flour used

If there a 4 cups in a pound then 5 pounds would be 5 * 4 = 20 cups of flour in 5 pounds.
20 cups - 11 cups = 9 cups of flour left over
B)9 cups
