The Medical Corporation of America has developed a new type of body temperature thermometer. The company expects to increase its sales by 25% over the past year due to this new development. Last year's sales were $150,000 at a selling price of $100 per unit. A safety stock of 35 units has eliminated stockouts. The manager would like to cut costs as much as possible and decided to implement the EOQ inventory management system in order to minimize the total costs of inventory. The cost of warehouse space is $2.5 per unit. Inventory handling expense is $1.50 per unit, and inventory insurance premium is $1.00 per unit. Ordering cost is $100 per order.
