Hello, I am working on a finance assignment and I don't know how to solve it. The question is "You have just bought a new security. It pays you zero dollars for the first five years and after that it pays you $5,000 every year for the next 5 years (the first payment of $5,000 takes place at the end of sixth year). What is the price of the security? (Annual interest rate is 10% for the first five years and it is 5 % from year five to year ten.)"
