3 Sales people

Explanation:

The calculation of total cost per shift is shown below:-

1st sales 2nd sales 3rd sales 4th sales

person person person person

Average Waiting

Time 10 minutes 6 minutes 3 minutes 2 minutes

Total waiting

Cost $720 $432 $216 $144

(72 * $1 * 10) (72 * $1 * 6) (72 * $1 * 3) (72 * $1 * 2)

Add: Total labor

Cost 80 $160 $240 $320

($80 * 1) ($80 * 2) ($80 * 3) ($80 * 4)

Total cost $800 $592 $456 $464

Thus, 3 servers have the lowest cost, so that the overall cost per change with 3 Sales people is chosen.
