The Gilbert Air-Conditioning Company is considering the purchase of a special shipment of portable air conditioners manufactured in Japan.

Each unit will cost Gilbert $75, and it will be sold for $130. Gilbert does not want to carry surplus air conditioners over until the following year. Thus, all surplus air conditioners will be sold to a wholesaler for $40 per unit. Assume that the air conditioner demand follows a normal

probability distribution with h = 21 and o = 9.

Note: Use Appendix B to identify the areas for the standard normal distribution. Round "cumulative standard normal probability" to two decimal places.
