# A fast-food restaurant has a drive-through window and during peak lunch times can handle a maximum of 50 cars per hour with one person taking orders, assembling them, and acting as cashier. The average sale per order is \$9.00. A proposal has been made to add two workers and divide the tasks among the three. One will take orders, the second will assemble them, and the third will act as cashier. With this system, it is estimated that 70 cars per hour can be serviced. Use productivity arguments to recommend whether to change the current system.

The answer is; I do not recommend the change of current system

Explanation:

The productivity of one person taking orders, assembling them, and acting as cashier is higher than that of 3 people.

The time frame is the same for both systems (1 hour), productivity is illustrated below;

Cars serviced by 1 person in existing system = 50/1 = 50

Cars serviced by 1 person in 3 employee system = 70/3 = 23.33

The system should not be changed.
