Question

Elevators have safety limits for how much weight they can lift. The elevator at the Terrace Hotel can hold up to 2,100 pounds. write an equation or inequality that represents the allowable weight on the elevator at the Terrace Hotel. Graph the solution to the equation or inequality you wrote on the number line. Explain your answer.

Answer 1

The maximum mass that elevator can lift is 2100 pounds. This means that mass must be equal to that or less than that. If we use m for allowed mass we can write this as:

`m \leq 2100 pounds`

The graph is given on the picture. The blue line marks maximum allowed mass, the red line marks actual mass. Grey part contains all allowed values of a mass.
