Question

Write an inequality and then solve.

9. A freight elevator can safely hold no more
than 2200 pounds. An elevator operator must
take 60-pound boxes to a storage area. If the
operator weighs 155 pounds, how many boxes
can be safely moved at one time?

Answer 1

Let the number of boxes be x.

The total weight of the boxes is 60x.

Adding the operator, the total weight is 60x+155, which is no more than 2200.

`60x+155 \leq 2200 \\ \\ 60x \leq 2045 \\ \\ x \leq 34.08333... \\ \\ \lfloor x \rfloor =\boxed{34}`
