please show proper steps and show workings where necessary.

Mayco Inc would like to set up a new plant. Currently, Mayco has an option to buy an existing building at a cost of $ 24,000 . Necessary equipment for the plant will cost $16,000, including installation cost. The project would also require an initial investment of Rs. $12,000 in net working capital. The initial working capital investment will be made at the time of the purchase of the building \& equipment. The project estimated economic life is four years. At the end of that time. The building is expected to have a market value of $15,000. Whereas the equipment is expected to have a market value of $4,000. Annual sales will be $80,000. The production department has estimated that variable manufacturing cost will total 60% of sales. And that fixed overhead cost, excluding depreciation will be $10,000 a year. The marginal federal - plus state tax rate is 40%, its cost of capital is 12% and, for capital budgeting purpose, the company policy is to assume that operating cash flow to occur at the end of each year. The plant will begin operations immediately after the investment is made, and the first operating cash flow will occur exactly one year later. For calculating depreciation assumes; 15 years life for building and 10 years life for equipment a) Straight line method b) Written down vale method (Building 10\%) and (Equipment 15\%) Compute Initial Investment outlay, operating cash flow over the project's life and the terminal year cash flows for Mayco's expansion project. Then determine whether project should be accepted using NPV analysis
