The owner of a golf shop in Myrtle Beach, South Carolina, must decide how many sets of beginner golf clubs to order for the coming tourist season. Demand for golf clubs is random but follows a Poisson distribution with the average demand rates indicated in the following table for each month. The expected selling price of the clubs is also shown for each month. May June July August September October
Average Demand   60   90    70   50    30   40
Selling Price $145 $140 $130 $110 $80 $60

In May, each set of clubs can be ordered at a cost of $75. This price is expected to drop 5% a month during the remainder of season. Each month, the owner of the shop also gives away a free set of clubs to anyone who makes a hole-in-one from a short practice tee next to the shop. The number of people making a hole-in-one on this tee each month follows a Poisson distribution with a mean of 3. Any sets of clubs left over at the end of October are sold for $45 per set.
