1………………….$500………………………….$2,000

2………………….$1,000………………………$1,500

3………………….$1,500……………………….$1,000

4…………………..$2,000………………………$500

Total…………….$5,000………………………$5,000

If Mark can get a return of 10% on his investments, which option would you recommend that he accept? (Use present value analysis, and show all computations).

4. You have just learned that you are a beneficiary in the will of your late Aunt Susan. The executrix of her estate has given you three options as to how you may receive your inheritance:
