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. Rachel: January, 19.8; February, 23.3; March, 16.5; April, 19.3. Gary: January, 17.1; February, 16.3; March, 17.2; April, 24.4. Hannah: January, 17.8; February, 21.8; March, 23.4; April, 16.9. Christopher: January, 17.4; February, 16.1; March, 15.4; April, 21.7.

Compute each employee's total sales (sum of the months shown):
- Rachel: 19.8 + 23.3 + 16.5 + 19.3 = 78.9
- Gary: 17.1 + 16.3 + 17.2 + 24.4 = 75.0
- Hannah: 17.8 + 21.8 + 23.4 + 16.9 = 79.9
- Christopher: 17.4 + 16.1 + 15.4 + 21.7 = 70.6

First-choice conflicts:
- 12 p.m. requested by Rachel and Hannah → Hannah wins (79.9 > 78.9).
- 9 a.m. requested by Gary and Christopher → Gary wins (75.0 > 70.6).

Remaining shifts (3 p.m. and 6 p.m.) go to Rachel and Christopher. Both prefer 3 p.m. over 6 p.m., so the higher-sales employee (Rachel, 78.9) gets 3 p.m.; Christopher gets 6 p.m.

Thus the correct assignment is:
9 a.m. – Gary; 12 p.m. – Hannah; 3 p.m. – Rachel; 6 p.m. – Christopher.

None of the provided choices (A–D) match this assignment exactly.
