Question

Juliet rented a car for one day from a company that charges $80 per day plus $0.15 per mile driven. If she was charged a total of $98 for the rental and mileage,

for how many miles of driving was Juliet charged?
(Assume there is no tax.)
A) 15
B) 120
C) 533
D) 633​

Answer 1

B) 120

Explanation:

m = miles

$98=$80+$0.15m

$98-$80=$80-$80+$0.15m

$18=$0.15m

$18/$0.15=$0.15m/$0.15

120=m

Juliet drove 120 miles for $98.

(this is a good explanation, I guess)

Answer 2

Option B) 120 miles

Explanation:

Company charges per day for a car rent = $80

and per mile driven = $0.15

Juliet rented a car for one day and she was charged a total = $98

Let Juliet traveled x miles

$80 + $0.15x = $98

0.15x = 98 - 80

0.15x = 18

x =
`(18)/(0.15)`

x = 120 miles

Juliet was charged for 120 miles driving.
