Question 945449: A 2003 Subaru Outback wagon costs $23,500 and gets 24 miles per gallon. Assume that gasoline costs $3 per gallon.

Correct: Your answer is correct. .

(b) Assume that the total cost of owning the car consists of the price of the car and the cost of gasoline. (In reality, the total cost is much more than this.) For the Subaru Outback, find a linear function describing the total cost, with the input variable being the number of miles driven (m).
C(m) =
Incorrect: Your answer is incorrect. .

This is the problem I am trying to solve. the first answer was correct at .13 but for the second answer I wrote c(m)=23500+.13m and it says its not correct. I am using web assign. I don't know how else to input it as the numbers seem correct so I think its my formatting.

The cost of the vehicle is distributed over the number of miles, so
$23500/mi+$0.13*mi where mi=miles driven
