1. You borrowed some money at 8 percent per annum. You repay the loan by making three annual payments of $ 239 (first payment made at t = 1), followed by five annual payments of $ 419 , followed by four annual payments of $ 842. How much did you borrow?

2. I plan to deposit $ 322 into my retirement every year for the next 25 years. The first deposit will be made today (that is, at t = 0) and the last deposit will be made at the end of year 24 (that is, at t = 24). I plan to make no other deposits. Assuming that I will earn 12.49 % p.a. on my retirement funds, how much money will I have accumulated 36 years from today (that is, at t = 36)? (Round your answer to 2 decimal places; record your answer without commas and without a dollar sign).
