1. Consider $4 tripling in value every six months. What's the resulting amount after 5 years? Round to nearest dollar.

2. You expect to receive $8,000 at the end of each year for the next ten years, followed by a single cash flow of $17,000 at the end of year 11. If the discount rate is 8%, what is the present value of this combined annuity? Round to the nearest dollar.

3. Consider a deferred annuity with 13 annual payments of $2,000 starting at the end of year 3 (first of 13 payments is at the end of year 3). If the discount rate is 9%, what is the present value of this deferred annuity? Round to the nearest dollar.
