A manufacturing firm has discontinued production of a certain unprofitable product line. Considerable excess production capacily was created as a result. Management is considering devoting this excess copacity to one or more of three products: X1. X2. and X3. Machine hours required per unit are The avaiable time in machine hours per week is The salespeople estimate thay can sell all the units of x1 and x2 that can be made. But the salespotential of x3 is 80 units per week maximum. Unit profits for the three products are 0. Set up the equations that can be solved to maximize the profit per week. (Leave no cells blonk - be certain to enter "0" wherever required.) b. Solve these equations using the Excel Solver. (Leave no cells blank - be certain to enter "O" wherever required. Round your answers to the neorest whole number.) c. How much of each constraint or resource is unused? (Leave no cells blank - be certain to enter "O" wherever required. Round your onswers to the neorest whole number.) d-1. Would the machines work at capacity? d.2. Wilt X3 be at maximum sales capacity? No Yes e. Suppose that an additional 300 hours per week can be obtained from the milling by working overtime. The incremental cost would be \$2.00 per hour. What would be the allowable increase (from the excel sensitivity report) in overtime when compared to additional hours that can be obtained? (Round "shadow price" to 2 decimal places and the rest to the nearest whole number.)
