Question

A delivery person uses a service elevator to bring books up to an office the delivery person 160lb and each box of books weighs 60lb the maximum capacity of the elevator is 1230lb

Answer 1

1450, I think you just have to add up

Answer 2

1230=160+60b

b=17.8

Since you can't take part of a box the limit would be 17 boxes since you don't want to go over a weight of 1230.
