1. You have $5000, and you want that money to triple in 15 years. The bank says that it has quarterly compounding. What needs to be the APR so that your money triples in 15 years?

2. You have deposited $1500 in an account. In the first year, the account pays a yearly interest rate of 8%, compounded annually. However, in the second year, it pays a yearly interest rate of 8%, compounded quarterly. How much will you have at the end of the second year?

3. Starting from today (t=0), you are saving $1,500 a year for the next three years (four investments in total). You want to spend your savings at the end of the third, fourth, and fifth year equally. If the market interest rate is 10%, how much can you spend at the end of the fifth year?
