About the case: The plastic company is trying to decide whether to use machine A or B in its plant. The company uses a 15% MARR Machine A has an initial cost of SR 150,000, requires annual maintenance costs of SR 15,000, and will last 10 years. . Machine B costs SR 250,000, requires SR 8,000 annual maintenance, and will last 20 years Question 1 Which option the company should choose to recover its initial cost: a) without considering time value of money, b) with considering the time value of money. Question 1 Which option the company should choose to recover its initial cost: a) without considering time value of money, b) with considering the time value of money. Question 2 An engineer at the company hypothesize that the service life has no merit in the comparison and can be assumed as perpetual. Which machine is best in this case? Question 3 The company would like to explore the following scenarios: Scenario1: If both machines operated for 10 years after which the machines will be sold. The salvage value for Machine A is SR 9.000, and SR 11,000 for Machine B. Scenario 2: If both machines operated for 20 years then the following assumptions are needed: Machine A would need to be overhauled at the end of its service life which will cost SR 33,500 and then the annual cost will decrease by 5% each year. The salvage value for Machine A is SR 5,000 for Machine A, and SR 6,000 for Machine B. . . Determine which machine is best in Scenario 1 and Scenario 2
