Chau is going to rent a truck for one day. There are two companies he can choose from, and they have the following prices. Company A charges $135 and allows unlimited mileage. Company B has an initial fee of $75 and charges an additional $0.80 for every mile driven. For what mileages will Company A charge less than Company B?

company A charge less than company B if y > 75 miles  

Explanation:

given data

Company A charges =  $135

Company B initial fee = $75

additional charge =  $0.80

solution

we consider here driving =  x mile

and mileages for company A charge less than company B = y

so

when Charges of company A = charges of company B than equation will be

$135  = $75 + $0.80 x    1

solve it we get x

x = 75

so here mileages for which company A charge less than company B is

y > 75

company B is better if the distance is < 75 miles  

company A is better if the distance is > 75 miles

the first one $24,630
