Setup costs for each product amount to $2,000 per order, and holding costs are based on a 25 percent annual interest rate. Find the optimal order quantities for these six items so that the storage space is never exceeded.
(Hint: Use a cell location for the Lagrange multiplier and experiment with different values until the storage constraint is satisfied as closely as possible).
