For this case we have to:

d: Let the variable representing the number of miles traveled per day

Then, the cost will be given by the following equation:


C (d) = 0.85d + 40

If we have the cost
C (d) = 91, then the number of miles traveled is:


91 = 0.85d + 40\\91-40 = 0.85d\\51 = 0.85d\\d = \frac {51} {0.85}\\d = 60

Thus, the number of miles traveled is 60.

Answer:


C (d) = 0.85d + 40

For a
C (d) = 91, the number of miles traveled is 60
