Answer:
the third function
Step-by-step explanation:
when looking at x=-1 the value goes from (x=-2) 0 to -3, when x=0 it goes to 0, and then only increases after that.
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
(21x- 19x) -10= 180
2x-10= 180
2x= 190
x= 95
hope this helps!
