EXERCISES

• 4-1 You decide to invest $100,000 in a program that is guaranteed to grow by 2.5% for each of the next 5 years. At the end of the 5 years, how much is your investment worth?

• 4-4 Suppose you deposit $100 in a savings account that compounds annually at 2%. After 1 year at this rate, the bank changes its rate of compounding to 1.5% annually. Assuming the compounding rate does not change for 4 additional years, how much will your account be worth at the end of the 5-year period?
