a truck can be rented from Basic Rental for $50 per day plus $0.20 per mile. Continental chargers $20 per day plus $0.50 per mile to rent the same truck. How many miles must be driven in a day to make the rental cost for Basic Rental better deal than Continenal's?

-----------------

Basic Rental DATA:

Cost = 5000 + 20x, where x = # of miles driven

---------------

Continental DATA:

Cost = 2000 + 50x

------------------

INEQUALITY:

Basic < Continental

50000 + 20x < 2000 + 50x

48000 < 30x

x < 1600 miles 

If # of miles driven in a day is < 1600 Basic will be a better deal than Continental.
