Question

Select the correct answer. The average salary of employees at a company is $40,000. For any given employee's salary, the maximum difference from this average is $5,000. Which inequality models the possible range of an employee's salary? A Ix-40,000 $5,000 B. Ix-5,000 $40,000 C. Ix+40,000 $5,000 D. x 5,000 $40,000

Answer 1

Explanation

Given that the average salary of employees at a company is $40,000 and that the maximum difference from this average for any employee salary is $5,000.

The inequality model that refers to this most therefore range between $35000 and $45000. That is

$35000\leq x\leq45000$

The above solution can then be compacted to give;

$\left|x-40000\right|\le 5000$

Answer: Option A
