Question

22. model each situation below with an equation. select the correct equation for each situation. then solve each problem. A company employs 72 workers. it plans to increase the number of employees by 6 per month until it has twice its current workforce. how many months will it take to double the number of employees?

Answer 1

12 months

Explanation:

A company employs 72 workers. It plans to increase the number of employees by 6 per month.

Let x = number of months when the company increases the number of workers. Then in x months, the number of workers increases by 6x and the total number of workers will be (72+6x).

They plan to increase the number of workers until it has twice its current workforce. So

`72+6x=2\cdot 72`

Solve this equation:

`72+6x=144\\ \\6x=144-72\\ \\6x=72\\ \\x=12`
