5 point for each problem.
Show all the calculations and formulas to receive credit for the answer,
1.1 A regional bank offers an investment with a nominal rate of interest of 7.5%.
. What is the effective rate if the investment is compounded continuously? . What is the effective rate if the investment is compounded daily?
. What is the effective rate if the investment is compounded annually?
1.2 Suppose you bought a year ago a $10,000 ten-year treasury note with $400 annual coupon, i.e., interest rate of 4% per annum compounded annually. You have already received the first coupon payment, so you are holding in effect a $10,000 treasury note with nine-year maturity. Suppose further that the market interest rate on nine-year treasury notes has now gone up to 5% (again, per annum with annual compounding) What is your treasury note worth? How much would it be worth if the interest rate had instead gone down to 3%?
1.3 Consider obtaining a loan in the amount of $2,000 with a maturity of 4 years. The loan requires you to make equal payments every 6 months. The annual interest rate for the loan is 6.75%. Using the outline of the table below, complete the table for each period over the maturity of the loan.

There are two approaches to evaluate this investment. Show the necessary calculations.
• Assume the interest rate ot 4.33%. Use present value analysis to determine which investment you should choose?
• Calculating the rate of returns of the investment, which investment would you choose and why?
1.5 Suppose you would like to retire in 15 years. To save for retirement, you deposit an amount A into the bank at the beginning of the next 180 months. After that period, you would like to withdraw $1,000 at the beginning of the following 300 months. Assume a nominal yearly rate of 7.5% compounded monthly. What amount does A have to be?
