We need 75 quarts of 3% butterfat milk. How much of 2% and 5% do we need to mix? (t = 2% and f = 5%)
A) t + f = 75
B) .02 t + .05 f = (.03 * 75)
B) .02 t + .05 f = 2.25
Solving for t and f:
t = 50 quarts of 2 % and
f = 25 quarts of 5%
Double-Check
50 * .02 = 1 quart of buttermilk
25 * .05 = 1.25 quarts of buttermilk
2.25 quarts divided by 75 quarts = 3 % buttermilk
Answer:
Step-by-step explanation:
Adding both equations will make it:
Putting x = 10 will make it:
= 3(1000)-40+1
= 3000-39
= 2961
