Question

a truck can be rented from Company A for $110 a day Plus 40 cents per mile. company B charges $80 a day plus 60 cents per mile to rent the same truck. how many miles must be driven in a day to make the rental cost for company A a better deal than company b's?

Answer 1

 

110 + 0.40 x >= 80 + 0.60 x

 

0.20 x >= 30

 

x >= 30 / 0.20

 

x >= 150 miles

 

More than 150 miles must be driven a day to make the rental cost for company A a better deal than company B
