Question

He truck is rented at $40 per day plus they charge per mile of use the truck travel 15 miles in one day and the total charge was 115 which equation can be used to find the X charge in dollars per mile traveled?

Answer 1

15x + 40 = 115

We set the equation to 115 because the total cost is $115.
We add the "+ 40" because of the $40 to rent the trailer for the day.
The 15x is because it represents the miles per hour (x) times the number of hours.

The number of hours times the charge per mile, plus the $40 to rent it, will equal $115.

Hope this helps!!

Answer 2

`115 = 15 x + 40`

the charge is $5 dollars per mile

Explanation:

He truck is rented at $40 per day plus they charge per mile of use the truck travel 15 miles in one day and the total charge was 115

LEt x be the charge in dollars per hour

Initial charge is 40 and 15 miles travelled in one day

total charge = 15x + 40

Given : total charge is 115

So the equation becomes

`115 = 15 x + 40`

Now we solve for x

Subtract 40 from both sides

`75= 15 x`

Divide both sides by 15

x= 5

so , the charge is $5 dollars per mile
