The dam will cost $7.5 million up front to build and will begin producing electricity the following year. The production of electricity is valued at $900,000/yr and the dam will produce a constant value for 17 years at which time it must be closed due to siltation.

1. If the real interest rate is 7%, what is the present value of the project? At 4%?

2. What is the annuity stream equivalent of this present value? At 7%? At 10 %
