Question

A delivery person uses a service elevator to bring boxes of books up to an office. The delivery person weighs 180 lb and each box of books weighs 40 lb. The maximum capacity of
the elevator is 850 lb. How many boxes of books can the delivery person bring up at one time?

Answer 1

Answer:

The delivery person can bring up max 16 boxes at one time.

Step-by-step explanation:

The elevator can only hold max 850 lbs, and the delivery man weighs 180 lbs.

850-180=670

That means the delivery man can have up to 670 lbs of boxes on the elevator.

670/40=16.75

Which means that the delivery man can hold up to 16 boxes max at one time.
