Question 424109
The charge for Avis is: 
A = 17.99 0.18M (M = number of miles)
For Hertz:
H = 18.95+0.16M 
Set A = H and solve for M
17.99+0.18M = 18.95+0.16M Subtract 0.16M from both sides.
17.99+0.02M = 18.95 Subtract 17.99 from both sides
0.02M = 0.96 Divide by 0.02
M = 48
The cost would be the same for 48 miles.
