macroeconomics help

I need help this macro economics question. I posted the wrong one earlier.

Fearful of what is currently happening in Raccoon City, you want to take some of your cash and invest it in order to obtain some returns. First, you are interested in investing in bonds. Suppose a company, the Umbrella Corporation, is issuing bonds today with a face value of $1,000 with a coupon rate of 8.95%, and a maturity of 10 years. a) Based on the lectures, describe the process of you buying the bond today and what will happen all the way until the bond matures. Be sure to include specific numbers, methodologies and concepts. b) Suppose one year has passed since you purchased the bond, and you want to sell it. Suppose that interest rates within the city have increased to 15.75%. What would be the fair market price for your bond that you initially bought? c) Suppose that interest rates actually decreased to 4.53% instead. What would be the fair market price for your bond? Now, you are interested in investing in the stock market. The Umbrella Corporation also has issued stocks, which has a current price of $89.32 per share. d) What would be a few reasons why you would invest in the stock market instead of the bond market? Provide a brief compare and contrast of the bond market and stock market. You are still thinking about your financial future and want to crunch a few numbers. Suppose that you need to purchase medical supplies and herbs and need to pay for it with your credit card. The interest rate on your credit card is 27.99%. a) You purchase $8,269.65 worth of supplies today. Assuming you do not make any payments on this amount, how much will you owe the credit card company 15 years later? You were also savvy with your investments, and invested your $15,000 in the Umbrella Corporation 30 years ago. The stock has returned you 9.85% compound interest over this period. b) How much will you have in your investment account based on this information
