Assume you are buying an insurance policy. The insurance policy is offering an annuity of $50,000 for 20 years that begins on your 66th birthday. If today is your 35th birthday and the opportunity cost is 6% per annum, how much should you pay for this insurance policy today? Present your answer as a whole number to two decimals (including the $ symbol) and a positive value, e.g. $3210.65 ( 25% marks will be deducted if the $ symbol is not provided)
