Demand for the compound is 0.6 million pounds per year. The fixed cost of setting up for a production run of the chemical is $1,500, and the variable cost of production is $3.50 per pound. The company uses an annual interest rate of 22% to account for the cost of capital, and the annual costs of storage and handling of the chemical amount to 12% of the value. Assume that there are 250 working days in a year. What is the optimal lot size, maximum inventory level, and total cost?
