Answer:
The answer is $3,456,000.
Step-by-step explanation:
Annuity is a set amount of money that is paid every year for the person's life. She is 35 years old and expected to live to 75. So for $10,000 at the end of each month, the annuity is, 40 x 12 = 480 months, 480 months x $10,000 = $4,800,000. If we take the $10,000 as the principal amount, and calculate the interest at 7,2% monthly, in 40 years it would be $3,456,000.
