Please explain and show the math as to why the two answers below are wrong.

One month prior to flu season, GammaFlu must decide how many doses of this year's flu vaccine to order from its contract manufacturer. GammaFlu sells the vaccines for $61 per unit. Any unsold vaccines at the end of flu season can be sold in a secondary market for $19. It costs $2 to hold a unit in inventory through the selling season. Demand is estimated to be normally distributed with a mean of 44,000 units and a standard deviation of 7,000 units. GammaFlu's contract manufacturer charges $30.2 per unit ordered.

Compute the Optimal Quantity and the Optimal expected profit.
