Question

A delivery person uses a service elevator to bring boxes of books up to an office. The delivery person weighs 190 lb and each box of books weighs 60 lb. The maximum capacity of the elevator is 1740 lb. How many boxes of books can the delivery person bring up at one​ time?

Answer 1

Answer:

25 boxes.

Step-by-step explanation:

We have the inequality:

190 + 60x ≤ 1740  where  x = the number of boxes of books.

60x  ≤  1740 - 190

60x   ≤  1550

x ≤ 25.83.

Answer 2

Answer:

25 boxes

Step-by-step explanation:

To get the amount of boxes of books that can be brought up, subtract the weight of the delivery person from the maximum capacity: 1740 - 190 = 1550 lbs left to fill by the boxes

To find the amount of books able to be brought up, divide the capacity left by the weight of each of the boxes: 1550/60 = 25.8 books able to be carried up, without exceeding, meaning that the delivery person can bring up 25 boxes of books without the service elevator collapsing

Hope this helps :)
