Question

To make 3 dozen cookies, a recipe calls for 4 eggs and 1/2 cup of chocolate chips. Ben wants to make 12 dozen cookies for a class picnic. How many eggs and how many cups of chocolate chips does he need?

Answer 1

One dozen = 12

3 dozens = 12*3 or 36

To make 36 cookies you need 4 eggs and 1/2cups of chocolate chips.

Ben wants to make 12 dozen or 144 cookies.

144/36 = 4

To find out how many chocolate chips and eggs he needs we can multiply the amount of chocolate chips and eggs it takes to make 3 dozen by 4 to find out how many chocolate chips and eggs he needs to make 12 dozen.

4 *4= 16 He will need 16 eggs

4*1/2= 2 He will need 2 Cups of chocolate chips.
