Your client wishes to insure their Lamborghini. PMA Insurance has quoted an annual premium to insure the car of $50,000. PMA offers two other payment methods. The account can be paid in full by making 12 equal end-of-the month payments of $4,500. Alternatively two semi-annual payments (the first immediately) of $26,000 can be made. The appropriate interest rate to make the comparison is 6% pa compounded monthly. Which of the three options should you choose for your client?
