Question 1147712: I need help creating A LINEAR FUNCTION that uses the # of miles as the input & provides the total car rental cost (including gas) for the entire trip as the output.
The car rental fee is $39.23 per day. Mileage fee of $.43 per mile. It is assumed the rental car gets 32 miles per gallon and gas costs $2.88 a gallon. I already have: f(x)=$.52 x (miles driven) + $___________
Using the f(x)= mx + b model, I can't get the second amount for the life of me! Answer by rothauserc(4718) (Show Source):
You can put this solution on YOUR website! f(x) = (x/32) * 2.88 + x * 0.43 +39.23
:
f(x) = 2.88x/32 +0.43x +39.23
:
f(x) = 0.09x +0.43x +39.23
:
f(x) = 0.52x +39.23
:
Therefore, f(x) gives you the total cost per day
:
The problem does not give you the number of days the car was rented for the trip
