These are FINA 365 (Corporate Finance) Questions.

1) You just received 100 gold coins from your grandparents, who purchased them at their face value ($100 in total) in 1975. These coins appreciate by 2.5 percent annually. If you decide to hold this coin collection to regift them to your grandchildren 55 years from now, how much will this collection be worth when that time comes? Explain your calculation in detail.

2) Your bank has just presented a plan: a 5% rate annually until you retire in 40 years. However, you think that interest rates will increase over the next year, and one year from today, you will have an opportunity to invest at 5.6% annually. If you plan to invest $16,000 either this year or next year, how much more will you have when you retire if you wait one year to make your investment?
