A delivery person uses a service elevator to bring boxes of books up to an office. The delivery person weighs 160 lbs and each box of books weighs 50 lbs. The maximum capacity of the elevator is 1000 lbs. How many boxes of books can the delivery person bring up at one time?
50x + 160 = 1000
50 + 160x = 1000
50x - 160 = 1000
50 - 160x = 1000
