The local bank offers to pay 6% interest on savings deposits. In a nearby town, the bank pays 1.50% per 3-month period (quarterly). A man who has $3000 to put in a savings account wonders whether the higher interest paid in the nearby town justifies driving there to make the deposit. Assuming he will leave all money in the account for 2 years, how much additional interest would he obtain from the out-of-town bank over the local bank? If there is a difference in the additional interest from local bank and out-of-town bank, could you explain why?
