A trailer is rented at $30 per day plus a charge per mile of use. The trailer traveled 25 miles in one day, and the total charge was $130. Which equation can be used to find the charge x, in dollars, per mile traveled?

Answer 1

Hazel Anglin

Equation is #25x+30=130#

The trailer was used for #25# miles.

Let charges per mile for trailer be #x#, in dollars, per mile

then charges for #25# miles are #25xx x=25x#

As rent per day is #$30#

and total charges are #25x+30#

As total charge was #$130#

equation is #25x+30=130#

The equation that can be used to find the charge ( x ), in dollars, per mile traveled is:

[ 130 = 30 + 25x ]

Where:

( 130 ) is the total charge in dollars.
( 30 ) is the base charge per day in dollars.
( 25x ) represents the charge for the mileage, where ( x ) is the charge per mile traveled in dollars.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
