The plant has an installation cost of $15 million, which will be depreciated straight-line to zero over its four-year life. If the plant has projected net income of $1,754,000, $1,820,500, $1,716,300, and $1,097,400 over these four years, what is the project’s average accounting return (AAR)?

Year |
Cash Flow |

0 | −$26,000 |

1 | 11,000 |

2 | 14,000 |

3 | 10,000 |

**Question 8. Calculating NPV[LO1]** For the cash flows in the previous problem, suppose the firm uses the NPV decision rule. At a required return of 11 percent, should the firm accept this project? What if the required return is 24 percent?

**Question 16.Problems with Profitability Index[LO1,7]** The Sloan Corporation is trying to choose between the following two mutually exclusive design projects:

Year |
Cash Flow (I) |
Cash Flow (II) |

0 | −$51,000 | −$14,400 |

1 | 24,800 | 7,800 |

2 | 24,800 | 7,800 |

3 | 24,800 | 7,800 |

1. If the required return is 10 percent and the company applies the profitability index decision rule, which project should the firm accept?

2. If the company applies the NPV decision rule, which project should it take?

**Question 17.** **Comparing Investment Criteria[LO1,2,3,5,7]** Consider the following two mutually exclusive projects:

Year |

3 | 85,000 | 25,000 |

4 | 572,000 | 19,000 |

1. If you apply the payback criterion, which investment will you choose? Why?

2. If you apply the discounted payback criterion, which investment will you choose? Why?

3. If you apply the NPV criterion, which investment will you choose? Why?

4. If you apply the IRR criterion, which investment will you choose? Why?

5. If you apply the profitability index criterion, which investment will you choose? Why?
