If the average adult produces $20,000 of output per year, how much global output is lost annually as a result of adult deaths from secondhand smoke

Here is the answer. If the average adult produces $20,000 of output per year, the amount of global output that is lost annually as a result of adult deaths from secondhand smoke is 48 billion dollars. Consider this:

600,000 total deaths

165,000 children

435,000 adults

435,00 times $110,00 output per year = $47,859,000,000 or $48 billion.
