<span>B. 16 quarts of the 2% milk and 24 quarts of the 7% milk
First, let's create an equation to solve.
x = quarts of 2% milk
(40-x) = quarts of 7% milk
So we have the equation
x*2 + (40-x)*7 = 40*5
Now to solve for x
x*2 + (40-x)*7 = 40*5
x*2 + 7*40 - 7*x = 40*5
x*2 - 7*x = 40*5 - 7*40
-5*x = - 2*40
x = 2*8
x = 16
So we need 16 quarts of 2% milk and 40-16 = 24 quarts of 7%, which matches option "B".</span>
Answer:
2 1/2 cups
Step-by-step explanation:
5 × (1/2 cup) = 5/2 cup = 2 1/2 cup
__
Or, you can add them up. You know from your study of fractions that two half-cups make 1 cup.
(1/2 cup) + (1/2 cup) + (1/2 cup) + (1/2 cup) + (1/2 cup)
= ((1/2 cup) +(1/2 cup)) +((1/2 cup) +(1/2 cup)) +(1/2 cup)
= (1 cup) + (1 cup) + (1/2 cup)
= (2 cup) + (1/2 cup)
= 2 1/2 cup
