[FONT=&quot][h=1]5.35 people out of 100,000 in a given country are victims of homicide per year. The average victim age is 50 years old. The average life-expectancy of a person living in that same country is 79.33 years. If one year in that country there are no victims of homicide what would the average life-expectancy for a person be in that year in which there are no homicides?[/h]
If someone can explain how they got to the answer that would be a great help. Thank you so much!

Assume that the total population is 10 million.

Then 535 people were victim of homicide.

non-victim population = 10^7 - 535

The total life-age of the victims = 535 * 50

The total life-age of the population= 79.33 * 10^7

The total life-age of the non-victim population= 79.33 * 10^6 - 535*50

continue.......

By the way - "between 2005 and 2012, the average homicide rate in the U.S. was 4.9 per 100,000 inhabitants compared to the average rate globally, which was 6.2." (wiki)
