0.85 M + 22.55

Step-by-step explanation:

We know that the total cost is the standard cost plus the insurance cost

C(M) = S(M) + I(M)

        = 17.75 + .60M + 4.80+.25M

Combine like terms

        = 0.85 M + 22.55

For this case we have that the standard charge, in dollars, of a company that rents vehicles is given by:

M: Number of miles traveled.

On the other hand, the insurance charge is given by:

If we want to find the total cost of renting the vehicle, we must add both equations:

We add similar terms:
