Milk is stocked at the grocery store each week. At the end of the week unsold milk is reduced in price by 60% and always sells for this lower price instantly. If weekly demand for milk is normally distributed with a mean of 300 gallons and standard deviation of 45 gallons, find the price for which a fresh gallon of milk sells. Assume a service level of 97.5% and that the store purchases milk for $2.44 per gallon.
