Tonga ways 150lb. he is loading a freight elevator with identical 72-pound boxes. the elevator can carry no more than 2,000 lb. if tonga rides up with the boxes, how many boxes can be loaded?

25 boxes can be loaded.

Step-by-step explanation:

Weight of Tonga = 150 lb

Weight of each box = 72 lb

Maximum weight the elevator can withstand = 2000 lb

Tonga rides along with the boxes.

Let the number of boxes be 'n'.

1 box weight = 72 lb

∴ 'n' boxes weight = 1 box weight × Number of boxes

∴ 'n' boxes weight =

Now, combined weight of boxes and Tonga =

Now, the total weight should not exceed the maximum capacity of the elevator.

∴ Combined weight ≤ Maximum Weight

⇒

Now, solving for 'n', we get:

So, the number of boxes should be less than or equal to 25.

Therefore, the maximum number of boxes that can be loaded are 25.
