Question

The cost of a car rental is thirty dollars a day plus fifteen cents a mile. If the total cost to rent the car was one hundred and eighty dollars, how many miles was the car driven if it was rented for four days?

Answer 1

Explanation:

Alright, lets get started.

Suppose car was driven x miles in its 4 days trip.

Cost of a car rental is thirty dollar per day.

So, for 4 days, the car rental will be =
`30*4=120` $

For 1 mile, it adds fifteen cents,

So, for x miles, the cost will be =
`0.15 x` $

As per question, total rent is 180 $

Total rent will be =
`120 + 0.15 x = 180`

Subtracting 120 in both sides

`0.15 x = 180-120=60`

`x=(60)/(0.15)`

`x=400`

It means car was driven 400 miles. : Answer
