A company is planning to invest in a new automated plastic-molding press. Four different presses are available. The initial capital investments and annual expenses for these four mutually exclusive alternatives are as follows: Press 1 Press 2 Press 3 Press 4 Capital investment (S) 24000 30400 49600 52000 Useful life (year) 3 5 5 5 Annual costs Power (S) 3720 2720 4800 5140 Labor (S) 26000 24000 16800 14000 Maintenance (S) 1800 2000 2800 2050 Property taxes and insurance ($) 500 1050 940 600 a. Assume that each press has the same output capacity (120,000 units per year) and has no market value at the end of its useful life; the selected analysis period is five years, and any additional capital invested is expected to earn at least 10% per year. Which press should be chosen if 120,000 non defective units per year are produced by each press and all units can be sold? The selling price is $0.375 per unit. Note: Show your answers in both hand and Spreadsheet (10 marks) AIM b. Suppose that each press is still capable of producing 120,000 total units per year, but the estimated reject rate is different for each alternative. This means that the expected revenue will differ among the alternatives since only non-defective units can be sold. The data for the four presses are summarized below: Project 1 Project 2 Project 3 Project 4 Capital investment (S) 24000 30400 49600 52000 Annual costs (S) 32020 29320 25450 22130 Rejected Rate 8.4% 0.3% 2.6% 5.6% Note: Show your answers in both hand and Spreadsheet (10 marks) c.
