A delivery person uses a service elevator to bring boxes of books up to an office. The delivery person weighs 150 lb and each box of books weighs 40 lb. The maximum capacity of the elevator is1060 lb. How many boxes of books can the delivery person bring up at one time?

We need to solve this

150 + 40N ≤ 1060 where N is the max number of boxes that can be brought at one time

Subtract 150 from both sides

40N ≤ 910 divide both sides by 40

N ≤ 22.75

So...22 boxes at one time [ if we can't bring "partial" boxes ]
