S-Curve Turntables manufactures turntables, and sells them through Hullabaloo Records, a chain of specialty record stores. For a model year, they will manufacture their newest model of turntable, called "Orbitz", which will be sold through the record stores. It costs $120 for S-Curve to manufacture the turntables, which it then sells to Hullabaloo for $200. Hullabaloo Records then sells the turntables at retail for $300. Whatever doesn't sell gets put on clearance for $100. Demand for the turntable is expected to be normally distributed with a mean of 1531 and a standard deviation of 278. What is the optimal order amount that will maximize the SUPPLY CHAIN'S expected profit?
