Your parents deposit $100 in your bank account on your 13th birthday. You spend none of it. Another $100 is deposited into your bank account on your 14th birthday - you withdraw $50 of it straight away. On your 15th birthday another $100 is deposited into your bank account, and don't spend any. If the interest rate is 4% p.a., how much money do you have in your bank account at the end of year 3?
