3) Four years ago, I loaned some money to Jack who made monthly payments of $10 on the loan which offeres me an annual interest rate of 12%. She paid it off today so I reinvested the proceeds into the stock of West Texas Cowboy Corp. which will make quarterly dividend payments of $20. My annual rate of return on the stock will be 8%. If I plan on selling the stock in 5 years for $800, how much must I have loaned Jack four years earlier? (HINT: HARD PROBLEM - DRAW A CASH FLOW TIMELINE!)
