Question

The mean hourly salary of the 10 employees at a fast­food restaurant is $8.25. One of the employees earning $6.50 an hour leaves the company, and another employee is hired at $5.50 an hour. What is the new mean salary of the employees?

Answer 1

You would add $8.25 + $5.50, which equals $13.75. Then you would divide that number by the number of employees currently working at the fast food restaurant; $13.75 / 2 = $6.875. So, $6.88 would be the new mean salary of the employees.
