Would love help with these two homework questions. Must be answered by using the computer (e.g QM Excel). Will upvote if effort has been made in the answer.

Problem 3. A fitter produces two types of fitting products-product A and product B using a cutting machine (cutter) and a grinding machine (grinder). Product A requires 4 hours of the cutter and 8 hours of the grinder; product B requires 6 hours of the cutter and 4 hours of the grinder. The cutter has processing hours of at most 300 hours and at least 200 hours. The grinder has maximum processing time of 250 hours. The cost involved in the production of product A is 8 and of product B is 12. The fitter expects that the combined production for products A and B must total at least 50 units. The fitter wants to determine the number of units of product A(x1) and product B(x2) that will minimize the cost of manufacturing. g. What is the impact of optimal solution if the demand is reduced to 45 ? (20 Marks) Problem 3.
