Problem 1: Assume a $4,000 investment and the following cash flows for two alternatives.
| Year | Investment   X | Investment   Y | 
| 1 | $1,000 | $1,300 | 
| 2 | 800 | 2,800 | 
| 3 | 700 | 100 | 
| 4 | 1,900 |   | 
| 5 | 2,000 |   |

b. Why do other methods allow for a better analysis? 
Problem 2: A ten-year bond pays 11% interest on a $1000 face value annually. If it currently sells for $1,195, what is its approximate yield to maturity? (Show all work/calculations/formulas)
