Abger Electronics, a retail store, restructures its employees’ schedules every six months. The employees are asked for their shift preferences, and the schedules are rearranged according to these preferences. When there is a conflict, those with the best total sales over the past six months are given priority. The following graph and table show the most recent sales records and employee preferences, respectively. A bar graph has month on the x-axis and sales (dollars times 1,000) on the y-axis.
