At a carnival, the carousel ride has a problem with keeping the mechanical horses working. Repair technicians can be hired at a rate of $30 per hour, while working as only one team. This means the technician will work alone. If two or more techs are hired they work together on the same job. One technician can fix a horse in an average time of 20 minutes with standard deviation of 20 minutes. Two techs can fix a disabled horse in an average time of 15 minutes with standard deviation of 15 minutes. When a horse is down lost income is $50 per hour. Horses tend to break down at the rate of 2 per hour with the time between two consecutive breakdowns following an exponential distribution.
