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?
