1. Suppose that one year from now you receive $100. At the end of the next nine years you receive a payment that is 1% larger than the prior year. If the cost of capital is 12% what is this stream of cash flows worth today?

2. Suppose that one year from now you will receive $400 and that at the end of every year thereafter you will receive a payment that is 3% larger than the prior payment. If the cost of capital is 7% what is this stream of cash flows worth today?

If the cost of capital is 8% how much should you be willing to invest in this opportunity?
