Please answer all of three questions

1. Our company wants to invest in equipment that will require an outlay of capital over two years. Upfront (year 0) is a cost of $200,000 and after year 1 there is an additional cost of $50,000. There will be a stream of earnings of $50,000, $100,000, $200,000, and $75,000 per year respectively, starting in year 2. The required rate of return is 12%. Should we invest in this project?

2. If we invest $1,000,000 today in a new product launch with an annual increase in sales of $75,000, what is the payback period? Is this a good project?

3. You have two projects, but can only select one of the two. Project A is $1,500,000 capital cost with $150,000 income stream starting in year 1 and going 5 years. Project B is $1,250,000 capital cost with $250,000 income stream for 5 years, but starting in year 2. Cost of capital is 9%. Which project, if any, should I pick and why?
