a
Step-by-step explanation:
it is being reflected of the other end
C = 10m + 30, where C is total cost and m is # of months
C = 10(5) + 30
C = 50 + 30
C = $80
$160 = 10m + 30
160 - 30 = 10m
130/10 = m
m = 13 months
Hope that helps

2z=-10
Now divide each side by 2z and you get
z= -5
So the answer is -5
