Office Automation must choose between two copiers, the NA$40$ or the HA$45.$ The NA$40$ costs less than the HA$45,$ but its economic life is shorter. The initial costs and maintenance expenses of these two copiers are given as follows: COPIER Year $0$ Year $1$ Year $2$ Year $3$ Year $4$ Year $5$NA$40-$RM$700-$RM$100-$RM$100-$RM$100--$HA$45-$RM$900-$RM$110-$RM$110-$RM$110-$RM$110-$RM$110$All cash flows occur at year$-$end and the discount rate is $12\%.$ Assume that revenues are the same regardless of the copier, and assume that whichever copier the company chooses, it will continue to buy that model forever. The salvage value of NA$40$ is RM$150$ while the salvage value of HA$45$ is RM$200.$ Which copier should the company choose if the tax rate is $24\%$ and the depreciation rate is $50\%$ in the first year, followed by $25\%$ per year thereafter?
