Final answer:
To calculate the annual net cost, surrender cost index, and net payment cost index per $1000 of life insurance at the end of 20 years, we use the given cost data.
Step-by-step explanation:
To compute the annual net cost per $1000 of life insurance at the end of 20 years, we need to calculate the total amount paid in premiums over the 20 years and subtract the accumulated values of the premiums and dividends at 5 percent interest. The net cost is then divided by the total amount of insurance ($10,000).
Next, to compute the annual surrender cost index per $1000 of life insurance at the end of 20 years, we divide the sum of the accumulated value of premiums and accumulated dividends by the accumulated value of the premiums.
Finally, to compute the annual net payment cost index per $1000 of life insurance at the end of 20 years, we subtract the accumulated value of dividends from the accumulated value of premiums and divide by the accumulated value of the premiums.
