Apublisher claims that the average salary paid at its company is $37,500 but it could differ as much as $4,500. write and solve an absolute value inequality to determine the range of salaries at this company.

|x − 37500| ≤ 4500; the salaries range from $33,000 to $42,000

|x − 37,500| ≤ 4500; the salaries are less than $33,000 or greater than $42,000.

|x − 37500| ≥ 4500; the salaries range from $33,000 to $42,000

|x − 37,500| ≥ 4500; the salaries are less than $33,000 or greater than $42,000.
