Question

A recipe for pie crust calls for two cups of butter to be added for each three cups of flour. If Jono needs to
make many crusts and has a total of 10 cups of flour, which of the following is closest to the number of cups
of butter he will need?
(1) 5 cups
(3) 7 cups
(2) 6 cups
(4) 8 cups

Answer 1

Answer:

7 cups of butter

Step-by-step explanation:

2 cups of butter for each three cups of flour

Let the number of butter cups for 10 cups of flour = x

2 cups of butter = 3 cups of flour flour

x = 10 cups of flour

Cross multiply :

3x = 10 * 2

3x = 20

x = 20 / 3

x = 6.666

x = 7 cups of butter (nearest whole number)
