Suppose you have accumulated $24,000 in credit card debt. If the interest rate on the credit card is 21.5% APR compounded monthly, how many years will it take off to pay off this debt if you pay $500 per month? (Answer to the nearest tenth of a year.) Suppose you plan to retire at age 70, and you want to be able to withdraw an amount of $85,000 per year on each birthday from age 70 to age 100 (a total of 31 withdrawals.) If the account which contains your savings earns 5 5% per year simple interest, how much money needs to be in the account by the time you reach your 70th birthday? (Answer to the nearest dollar)
