what is the inequality?

Question

A worker is taking boxes of tile on an elevator. Each box weighs 62 lbs and the worker weighs 190 lbs. The elevator has a 2-ton weight limit. How many boxes of tile can the worker safely take on each trip?

Answer 1

Hi Aziza, the inequality to solve is: 190 + 62x ≤ 4000, where x is the number of boxes the worker can put on the elevator at one time.

 

190 + 62x ≤ 4000

 

62x ≤ 3810

 

x = 61

 

The worker can put 61 boxes plus himself on the elevator at one time.
