Lori rented a car for one day. The daily rental rate was $12.50 plus 25 cents per mile. The total cost of her rental was $46. Ho

Leona [35]

Answer:

The number of miles Lori drive be 134 miles .

Step-by-step explanation:

Let us assume that the number of miles Lori be x.

As given

Lori rented a car for one day.

The daily rental rate was $12.50 plus 25 cents per mile.

As 1 dollar = 100 cent

$1\ cent = \frac{1}{100}\ dollar$

$25\ cent = \frac{25}{100}\ dollar$

$25\ cent = 0.25\ dollar$

As given

The total cost of her rental was $46.

Than the equation becomes

46 = 12.50 + 0.25x

46 - 12.50 = 0.25x

33.5 = 0.25x

$x = \frac{33.5}{0.25}$

x = 134 miles

Therefore the number of miles Lori drive be 134 miles .
