Answer:
The numerator of the rational expression represents:
- Total cost of the truck when it is rented for a three day period.
Explanation:
x represent the number of miles driven during the rental period.
Also, the fixed charge of the truck when it is rented for a three day period is: $ 115
The charge per mile is: $ 0.83
This means when the car is driven x miles in three day period then the cost is: $ 0.83x
Total cost of the truck in the rental period is: 115+0.83x
This means that the average cost per mile for a three-day period is :
Ratio of total cost of truck to the number of miles driven.
i.e.
Hence, the numerator represent Total cost of truck during the rental period.
