Consuela owns a catamaran that she purchased five years ago for $$100,000.$ When cruise ships visit her city she does snorkeling trips for the tourists. The catamaran is being depreciated straight$-$line over its $10-$year expected life and is currently worth $$35,000.$ It is expected to have no value at the end of its life in five years. She is considering moving to a larger boat that can accommodate more people. She has found a deal on a nice used boat for $$125,000.$ The new boat would be depreciated straight$-$line over its five year life. Consuela expects that revenues would increase by $$50,000$ per year, but she will have to hire more crew to work with the drunken tourists and use more fuel, so expenses will increase by an expected $$12,500.$ She expects that the new boat would actually be worth $$20,000$ in five years. Consuela's marginal tax rate is $30\%$ and her required rate of return is $15\%.$ What is the NPV of the project?
