Question

a freight elevator CAN safely hold no more than 2000 Pound. an elevator operator must take 55lb boxes to a storage área. if he weighs 165 pounds how many boxes CAN he safely move at one time.

Answer 1

33 boxes.

Explanation:

We have been given that a freight elevator can safely hold no more than 2000 pound. Weight of elevator operator is 165 pound. Weight of each box is 55 pound.

Let n be number of boxes. We will write an inequality as weight of elevator operator and weight of all boxes should be no more than 2000 pound.

`55*n+165\leq 2000`

Now we will solve our inequality to find number of boxes that could be moved safely at one time.

`55*n\leq 2000-165`

`55*n\leq 1835`

`n\leq (1835)/(55)`

`n\leq 33.363636`

Therefore, 33 boxes can be moved safely at one time.
