You ride in a taxi to the airport. The taxi charges a flat fee per ride, plus a per mile rate for each mile driven. The function C=0.4m+5 gives the total cost C in dollars after a ride of m miles. What is the flat rate per ride? What is the per mile rate?

The flat rate is 5 and the rate per mile is .40 because you can replace m for any mile.
Regardless of how many miles he drives the flat fee will be $5

Suppose he drive 2 miles. 0.40*2 + 5

.80 + 5 = $5.80
