Question

Craig is delivering boxes of paper to each floor of an office building. Each box weighs 64 pounds, and Craig weighs 160 pounds. If the capacity of the elevator is 2000 pounds, what is the maximum number of boxes he can deliver on each elevator trip?

Answer 1

Solve:-

2000 - 160 = 1840

1840 ÷ 64 = 28.75

So, Craig can deliver about 28 boxes on each elevator trip.

Answer 2

If the maximum load on the elevator is 2,000 pounds,
and Craig weighs 160 pounds, that leaves

(2,000 - 160) = 1,840 pounds for paper.

If each box weighs 160 pounds, then how many boxes
can he carry without going over the 1,840-pound limit ?

(1,840 / 64) = 28.75 .

28 boxes weigh 1,792 pounds, and 29 boxes weigh 1,856 pounds.

28 boxes will leave him with 48 more pounds of capacity,
but 29 boxes would weigh too much.

He should take 28 boxes with him on each trip, and then,
on the last trip, he can use the extra 48 pounds allowed
to take his lunch up with him.
