Forecasting and inventory "Len's Scrubby Buggy" is a franchisee of Big Car Wash Supply (BCWS). The regional service manager comes to your store first thing in the morning every Monday to deliver the proprietary wash chemicals along with taking your order for the next week. BCWS has invested heavily in technology to utilize advanced chemicals to produce a clean that is "out of this world". While the products are outstanding, the downside is the shelf life of chemicals is no more than 10 days after delivery. Each concentrated tub of chemicals can wash 250 cars and costs $100. Len estimates the cost to place an order is $10 and the holding cost per unit is 1% of the cost. BCWS gives a 10% volume discount for 15 or more tubs of chemicals. How much are you ordering next week, and what is forecast for the following week. Explain your answer.
