You must evaluate the purchase of a proposed spectrometer for the R&D department. The base price is RM$140,000,$ and it would cost another RM$30,000$ modify the equipment for special use by the firm. The equipment would be sold after $3$ years for RM$60,000.$ The applicable depreciation rates are $33\%,45\%,15\%,$ and $7\%.$ The equipment would require an RM$8,000$ increase in net operating working capital $($spare parts inventory$).$ The project would have no effect on revenues, but it should save the firm RM$50,000$ per year in before$-$tax labor costs. The firm's tax rate is $40\%.$

$($i$)$ Compute the investment outlay for the spectrometer in year $0.$

$($ii$)$ Compute the project's annual cash flows in year $1,2,$ and $3.$

$($iii$)$ Compute the terminal value.

$($iv$)$ If the WACC is $12\%,$ should the spectrometer to be purchased? Explain.
