One car rental company charges $30 per day plus $0.25 per mile driven. a car company charges $40 per day plus $0.10 per mile driven. how many miles must you drive for a one-day rental at the second company to be less expensive than the same rental at the first company? write an inequality to solve.
Accepted Solution
A:
Rewrite the question into equations: let's say x is the miles you drive for a day the first company's rental charge= $30+$0.25x the second company's rental charge= $40+$0.10x
Calculate what the x is when two equations are equal to each other: $30+$0.25x=$40+$0.10x $0.25x-$0.10x=$40-$30 $0.15x=$10 x=$10/$0.15 x=66.667 miles
at least 66.667 miles. I am not sure though. I'm a little bit tired today, so you might want to check it yourself.
