b) A furniture factory makes wooden tables, chairs, and armoires. Each piece of furniture requires three operations: cutting the wood, assembling, and finishing. Each operation requires the mumber of hours (h) given in Table 3 below. The workers in the factory can provide 300 hours of cutting, 400 hours of assembling, and 590 hours of finishing each work week. How many tables, chairs, and armoires should be produced so that all available labor-hours are used? Or is this impossible?

Table 2: Profit per car
i) Assuming that all cars produced were sold, giving your answer in tabular form; caleulate the daily
profits from each plant for both January and February? [Hint: Represent the given informations
in matrices and perform matrix multiplication]
ii) What was the daily profit in January from the Windhoek plant?
i) What was the total daily profit (from all three plants) in February?
b) A furniture factory makes wooden tables, chairs, and armoires. Each piece of furniture requires three
