The average cost per mile for a three-day period is given by the rational expression , where x is the number of miles driven during the rental period. What does the numerator of the rational expression represent?

Respuesta :

Answer:The numerator represents the total cost for renting the truck over a three-day period.


Step-by-step explanation:


Answer:

The numerator of the rational expression represents:

  • Total cost of the truck when it is rented for a three day period.

Step-by-step 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.

[tex]Average\ cos\ per\ mile=\dfrac{115+0.83x}{x}[/tex]

Hence, the numerator represent Total cost of truck during the rental period.
