Answer:
30 gallons of 6% milk, and 45 gallons of 1% milk.
x=quarts of 6% butterfat
First, write an equation.
0.06x+0.01(75-x)=0.03*75
Multiply both sides by 100.
0.06x*100+0.01*100(75-x)=100*0.03*75
Simplify
6x+75-x=3*75
6x+75-x=225
Solve
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.

Answer:
Step-by-step explanation:
Solution,
Here
Mean=10
N=6
Efx=7+14+6+p+8+14
=49+p
Now
Mean=Efx/N
or,10=49+p/6 ( Therefore,10 is multiplied to 6)
or,60=49+p
or,p=60-49
p=11
