Answer:
30 gallons of 6% milk, and 45 gallons of 1% milk.
Step-by-step explanation:
x=quarts of 6% butterfat
<h2>First, write an equation.</h2>
0.06x+0.01(75-x)=0.03*75
<h2>Multiply both sides by 100.</h2>
0.06x*100+0.01*100(75-x)=100*0.03*75
<h2>Simplify</h2>
6x+75-x=3*75
6x+75-x=225
<h2>Solve</h2>
5x=225-75=150
5x=150
x=30
75-30=45
So, we need 30 gallons of 6% milk, and 45 gallons of 1% milk.
