Management is contemplating the purchase of a new oven which cost $25,000 with an estimated salvage value of zero. Expected before tax cash savings from the new oven are $4,000 a year over its full depreciable life. Depreciation is computed using straight line over a 5 year life, and the cost of capital is 10%. At the end of the oven's life, it can be sold for $2,000. Assume a 40% tax rate. What is the net present value of the new oven? IRR? (10 marks)
