Answer:
Bailey family's sprinkler was used for 35 hours and Harris family's sprinkler was used for 20 hours.
Step-by-step explanation:
Set up a system of equations.
Let be "b" the time Bailey family's sprinkler was used and "h" the time Harris family's sprinkler was used.
Then:
You can use the Elimination method. Multiply the first equation by -15, then add both equations and solve for "h":
Substitute 
into an original equation and solve for "b":
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.
