Question 1087992: A rental car company offers two rental plans, Plan A and Plan B, for the same economy size car. For both plans, the total rental cost, ƒ(m) is a function of the number of miles, m, that the car is driven. In addition to a flat fee of $75, Plan A offers a rate of $0.20 per mile for an unlimited number of miles. Plan B offers a higher mileage rate of $0.35 per mile but does not charge a flat fee for the rental.
I got the following solution for Plan A which is
t = f(m).20 + .75
and
t = f(m).35 but the rest I can not figure out because it doesn't come out right what am I doing wrong

First of all, it seems you are mixing dollars and cents. The fixed cost should be 75, not 0.75.
Your equations should read:
Plan A: f(m) = 0.20m + 75
Plan B: f(m) = 0.35m
If you wanted to use these to find, for example, at what mileage do the two plans cost the same, you would set the cost equal and solve for m
