Question 1167836: The cost of renting a car for one day is $39 plus 30 cents per mile. Write the average cost
per mile 𝐶 as a function of the number of miles driven in one day 𝑥. Graph the function
for 𝑥 > 0. What happens to 𝐶 as the number of miles gets very large? Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! Cost=$39+$0.30x
C= (1/x)($39+$0.30x)=(39/x)+(0.3x/x)=(39/x)+0.3
as x gets very large the average cost per mile gets smaller and approaches $0.3 per mile, since the 39 will become irrelevant.
The ordinate scale for the graphs below is from -5 to 100, -5 to 10 and from -1 to 1.
