Atruck can be rented from company a for $120 a day plus $0.40 per mile. company b charges $50 a day plus $0.50 per mile to rent the same truck. find the number of miles in a day at which the rental costs for company a and company b are the same

The number of miles in a day where the rental cost for company a and for company b should be the same is 700 miles.

Given that,

Now the following equation should be made

$120 + $0.40x = $50 + $0.50

$120 - $50 = $0.50 - $0.40x

$70 = $0.10x

x = 700 miles

Therefore we can conclude that the number of miles in a day where the rental cost for company a and for company b should be the same is 700 miles.
