question 1 is at the bottom

2) Consider the information from 1). Now assume you pay a 25% tax on interest income. What is your after-tax real rate of interest? 3) A bond has a par value of $1,000. Its coupon interest rate is 7%. The bond makes interest payments annually. What is the dollar amount of interest it pays every year? 4) A bond pays $100 in one year (no coupons). The interest rate is 6%. a. What is the price of the bond today? b. Now assume the rate goes up to 8%. What is the price now? c. Now assume the rate goes down to 4%. What is the price now? d. What is relationship between the change in interest rate and the change in bond price? 5) A zero-coupon bond has only one cash payment: the payment of its par value at maturity. Say a zero-coupon bond has a par value of $100, the interest rate is 5%, and the bond matures in 3 years. What is the price of the bond today? 6) A bond matures in four years. It has par value of $1,000 and a coupon rate of 5%. The current market rate of interest for that type of bond is 9%. a. What is the price of the bond today? b. Assume the current market rate of interest for that type of bond goes to 5%. Now what is the price of the bond? Answer the following questions using Excel. Print and turn in spreadsheet. Since issuance intoroctears. The coupon rate is 11%, paid annually. The par value is $100. Since issuance, interest rates have dropped and the market rate of interest for this type of bond is now 7%. What is the price of the bond today? 8) For this problem, use Excel's IRR function. (You can look under the formula menu to learn how to use it. Or use help function.) What is the intemal rate of return of the following cash flow stream? Show answer to two decimal places. 1) The market rate of interest is 6%. The inflation rate is 5%. What is the real rate of interest
