If someone can explain to this me how they got this answer please

A parent is evaluating a $250,000 term life policy vs. a $250,000 whole life policy. Over the next 25 years, the term policy will cost $10 month, and build no cash values. The insurance agent informs the parent that the whole life policy will cost $100 per month, but ill build guaranteed cash values of $75,000 at the end of 25 years. The parent assumes that he/she can invest the $90 per month difference in a mutual fund and earn 10% per year for the next 25 years. What is the future value of the mutual fund at the end of 25 years assuming end of the period deposits of $90 per month at a 10% interest rate; and how does it compare to the whole life cash value investment return (ignoring taxes)? If you get this right, I guarantee you will run circles around any life insurance agent you meet!!! The mutual fund will be worth $100,900.97, implying that the return on the whole life policy is less than 10% The mutual fund will be worth $100,900.97, implying that the return on the whole life policy is greater than 10% The mutual fund return will be worth $119.415.01, implying that the return on the whole life policy is less than 10% The mutual fund return will be worth $8,851.24, implying that the return on the whole life policy is greater than 10%
