Setup cost is $420, and storage and handling costs are $200 per tonne per year. The company operates 260 days a year. (Note: 1 tonne =1,000kg ). a. What is the optimal number of bags per production run? (Round your intermediate calculations to 2 decimal places and the final answer to the nearest whole number.) Optimal number of bags b. What would the average inventory level be for this lot size? (Round your intermediate calculations to 2 decimal places and the final answer to the nearest whole number.) Average inventory bags c. Determine the approximate length of a production run, in days. (Round the intermediate calculations and final answer to 2 decimal places.) Run length days d. About how many production runs per year would there be? (Round your intermediate calculations to 2 decimal places and the final answer to 1 decimal place.) Runs per year e. How much could the company save annually in inventory control cost if the setup cost could be reduced to $210 per production run and the optimal production quantity is recalculated and used? (Round the intermediate calculations and final answer to 2 decimal places.) Annual Savings
