An auto dealer believes that demand for 2015 model cars will be normally distributed with a mean of 200 and a standard deviation of 30. His cost of receiving an Envoy is $25,000, and he sells an Envoy for $40,000. Half of all the Envoys not sold at full price can be sold for $30,000. He is considering ordering 200, 220, 240, 269, 280, or 300 Envoys.

Using ~1750 random estimates, how many should he order?
