Answer:
William's human life value is $498,400
Explanation:
Given
Time = 20 years
Average Earnings = $80,000
Family Support = $40,000
Dollar Value = $12.46
To calculate a human life value, it is very important to deduct the Income tax costs from a person's average annual earnings.
Since William doesn't have any outstanding loan;
His Human Life value is calculated as follows;
HLV = (Annual Earnings - Family Support) * Dollar Value
HLV = ($80,000 - $40,000) * 12.46
HLV = $40,000 * 12.46
HLV = $498,400
