The Chill Delights Ice Cream Stand (CDICS) is preparing to serve ice cream to its customers. They estimate the demand for ice cream cones next weekend to follow a normal distribution with a mean of 300 cones and a standard deviation of 50 cones. CDICS needs to order ice cream cones in advance for $3 per cone. They sell each cone for $5. If there are unsold cones at the end of the day, the ice cream supplier will purchase them back for $1 per cone, which they will use for their employees. How many ice cream cones should CDICS order to meet demand while minimizing costs
