A delivery person uses a service elevator to bring boxes of books up to an office. The delivery person weighs 140 lb and each box of books weighs 60 lb. The maximum capacity of the elevator is 1330 lb. How many boxes of books can the delivery person bring up at one time?
To find out how many boxes of books the delivery person can bring up at one time, we need to subtract the weight of the delivery person from the maximum capacity of the elevator and then divide that by the weight of each box.
Total weight the elevator can hold = Maximum capacity - Delivery person's weight
= 1330 lb - 140 lb
= 1190 lb
Number of boxes of books the delivery person can bring up = Total weight the elevator can hold / Weight of each box
= 1190 lb / 60 lb
≈ 19.833 boxes
Since we can't divide a box, the delivery person can bring up a maximum of 19 boxes of books at one time.
Total weight the elevator can hold = Maximum capacity - Delivery person's weight
= 1330 lb - 140 lb
= 1190 lb
Number of boxes of books the delivery person can bring up = Total weight the elevator can hold / Weight of each box
= 1190 lb / 60 lb
≈ 19.833 boxes
Since we can't divide a box, the delivery person can bring up a maximum of 19 boxes of books at one time.
