Question 3 (25 marks) Aldersley Ltd is evaluating the investment in new machinery to manufacture Product A. Machine X is being considered to manufacture Product A. The following table shows the expected production units of Product A: Product A Year 1 19 000 Year 2 20 000 Year 3 20 000 Year 4 19 000 Product A will sell for N$20 per unit and will have variable costs of N$10 per unit. Fixed costs (inclusive of straight-line depreciation of the machine) will be N$90 000 per annum for product A. The unit selling price, all annual fixed and unit variable costs will remain constant over the four-year period. The machine under consideration will cost N$310 000 and it will have a residual value of N$30 000 after 4 years of use. The company has a cost of capital of 10% per annum.
