You plan on depositing $10,000 at the end of each year for 30 years into a retirement account that pays 5% interest. How much could you withdraw annually in equal beginning of year amounts starting at the time you make your last deposit and continuing for a total of 20 years, assuming balances continue to earn 5% until withdrawn? Suppose you borrowed $15,000 at a rate of 9% and must repay it in 5 equal installments at the end of each of the next 5 years. What is the outstanding balance of the loan at the end of second year?
