Question 159345: Hi, Can someone please help me with these problems. I've tried to solve them and having a VERY HARD time. PLEASE, PLEASE!! Thank you,
1. You are planning to deposit $10,000 today into a bank account. Five years from today you expect to withdraw $7,500. If the account pays 5% interest per year, how much will remain in the account eight years from today?

2. What is the value (price) of a bond that pays $400 semiannually for 10 years and returns $10,000 at the end of 10 years? The market discount rate is 10% paid semiannually.
3. Combs, Inc. is issuing new common stock at a market price of $22. Dividends last year were $1.15 per share and are expected to grow at a rate of 7%. Flotation costs will be 5% of the market price. What is Combs, Inc.’s cost of external equity?
4. Frank Zanca is considering three different investments that his broker has offered to him. The different cash flows are as follows:
End of Year A B C
1 300 400
2 300
3 300
4 300 300 600
5 300
6 300
7 300
8 300 600
Because Frank has enough savings for only one investment, his broker has proposed the third alternative to be, according to his expertise, the best in town. However, Frank questions his broker and wants to eliminate the present value of each investment. Assuming a 15% discount rate, what is Frank's best alternative?
