Question

A delivery person uses a service elevator to bring boxes of books up to an office. The delivery person weighs 170 lb and each box of books weighs 50 lb. The maximum capacity of

the elevator is 1460 lb. How many boxes of books can the delivery person bring up at one time?

Answer 1

Answer: 25.8 boxes (or 25 boxes if not allowing for partial boxes)

Step-by-step explanation: Let x = the number of boxes. Set up an inequality where the max number of pounds is 1,460. We know the weight of the delivery person, as well as the weight of one box, so

50x + 170 <= 1,460

50x <= 1,290

x <= 50/1,290

x <= 25.8 boxes
