Question

A car rental company charges $42 per day for a rented car and $0.75 for every mile driven. A second car rental company charges $48 per day and $0.50 for every mile driven.

What is the number of miles at which both companies charge the same amount for a one-day rental?
24 miles
72 miles
180 miles
360 miles

Answer 1

First car rental-
24 miles= 18
24x0.75
72 miles=54
72x0.75
180 miles=135
180x0.75
360 miles= 270
360x0.75


Second car rental-
24 miles=12
24x0.50
72 miles=36
72x0.50
180 miles=90
180x0.50
360 miles= 180$
360x0.50

Answer 2

42+(0.75×24) = 60

48+(0.50×24) = 60
