Please use excel to find the solution. More this question is from the concept of Lagrange multiplier from inventory and warehouse, to find the budget and space constraints. A local store has to display three products: Product X, Product Y, and Product Z. The data of these times are given in the following table. The annual interest rate used for computing holding costs is 25 percent. What are the optimal quantities that should be purchased of these three products if a. there is only budget constraint of $50,000 b. there is only space constraint of 2,750 square feet c. there are space constraint of 2,750 square feet and budget constraint of $50,000.
