Part I: Payoffs Table (15 points)

During the summer, a ski shop in Zurich must determine how large its order for skis must be for the coming winter season. The shop manager can make a small, medium, or large order for skis. The demand for skis and subsequent sales will be a result of the amount of snowfall at the nearby mountain lodges. The following payoffs table shows the sales for varying amounts of snowfall and order sizes.

Order Size	Light Snowfall	Average Snowfall	Heavy Snowfall
Small	$4000	$5700	$7200
Medium	$2400	$8000	$10,500
Large	-$1600	$4200	$12,000
