Answer:

The number of boxes = 13

Step-by-step explanation:

Given the weight of the delivery person =160 lb

The weight of each box of books=40 lb

maximum capacity of the elevator=710 lb

Let the max number of boxes of books be x. Now the total weight of the boxes and the delivery person should not exceed the maximum capacity of the elevator.

$40*x+160$

$40*x$

$x$

Therefore the maximum value of x is 13(since it is an integer).
