The weekly rental cost of a 20 foor recreational vehicle is $129.50 plus $0.15 per mile.
-Find a linear function that express the cost C as a function miles driven m.
- What is the rental cost if 860 miles are driven?
-How many miles were driven if the rental cost is $213.80?

  • Math -

    Start by writing an equation
    Total cost = (Fixed cost) + (Mileage charge)*(Number of miles)
    Choose appropriate symbos for your terms such as
    T = F + M N

    in which case F would be $129.50 and M would be 0.15

    Solve the equation for T when N = 860
    Solve the equation for N when T = 213.80
