Intro The Weather Company manufactures and sells 100,000 umbrellas per year at an average price of $20. It currently uses a machine that makes each umbrella at a variabe cost of $10. The machine has a book value of $100,000 and has 5 years left in its economic and accounting life. Its annual depreciation is $20,000. It could be sold now for $80,000, but won't have any value in 5 years. The company could replace the old machine with a new machine that costs $800,000. The new machine produces the same number of umbrellas at a variable cost of $9, has a life span of 5 years and is to be depreciated on a straight-line basis to a salvage value of $80,000. Since the machine can make higher-quality umbrellas, the average sale price would increase to $22 The project's discount rate is 9% and the company's marginal tax rate is 21% Attempt 130 for 10 pts. Part 1 What is the annual cash flow in years 1 to 5 with the new machine? 0+ decimals Submit Attempt 1/30 for 10 pts. Part 2 What is the cash flow from salvage value from selling the old machine now? 0+ decimals Submit Part 3 Attempt 1/30 for 10 pts. What is the NPV of selling the old machine and buying the new machine (ignore the old machine otherwise, i.e., don't calculate incremental cash flows)? 0+ decimals Submit Part 4 Attempt 1/30 for 10 pts. What is the NPV of replacing the machine instead of keeping the old one? 0+ decimals Submit
