Suppose you are planning to spend $1766 annually for vacation during the next 30 years. You are offered to pay $30,000 now so that annual expenses of your vacations for the next 30 years will be taken care of. The annual interest rate is 6%. Calculate the amount that is saved if you pay $1766 annually instead of $30,000 now (Hint: calculate 30,000 - PV($1766 paid annually)).
