The current demand is 40 customers per day. Mr. Mo expects that the demand grows to 50 customers per day with the promotion. The shop has four technicians and they receive $15 per hour. In addition to the labor cost, the shop incurs overhead that is 1.2 times the labor cost and the equipment cost that is $10 per customer. The shop operates 8 hours per day. In order to meet the larger demand, Mr. Mo considers the following three options:

Option A: Overtime	The current four technicians will work for two extra hours. They will be paid extra 10 dollars per hour for the overtime. As a result, the average hourly wage will become $17. The calculated is as follows: 8 hours$15+2 hours$2510 hours=$17 per hour
Option B: New hire	The shop will hire one technician. The work hours and wage for the new technician will be the same as for the current technicians.
Option C: Equipment upgrade	The shop upgrades equipment. With the upgrade, the equipment cost will increase to $15 per customer. However, the shop will be able to process all customers (50 customers per day) within the regular work hours (8 hours per day).

The important information is summarized in Table 4:
