First refrigerator cost
C(x1)=700+85x
C(10)= 700+850
C(10)= 1550
refrigerator 2nd
C(x2) = 1000+25x
C10) =1000+250
C(10)=1250
Now you know it.
same cost
700+85x=1000+25x
60x=300
x= 5 years
7v = 2v - 20
First, subtract 2v from both sides. / Your problem should look like: 7v - 2v = -20
Second, simplify 7v - 2v to 5v. / Your problem should look like: 5v = -20
Third, divide both sides by 5. / Your problem should look like: v =
Fourth, simplify

to 4. / Your problem should look like: v = -4
Answer:
v = -4
7-(-3)=10
3-(-2)=5
