a) Titiwangsa Corporation is using a computer where its original cost was RM25,000. The machine is now 5 years old and has a current market value of RM5,000. The computer is being depreciated over a 10-year life toward zero salvage value. Depreciation is on straight line basis. Management is contemplating to purchase a new computer which will cost RM50,000 and the estimated salvage value is RM1,000. Expected savings from the new computer is RM3,000 a year. Depreciation is on straight line basis over a seven-year life and the cost of capital is 10%. If the tax rate is 50%, should the firm replace the asset?
