Starting at the age of 40, an average man loses 5%of his hair every year. At what age should an average man expect to have half his hair left?

29. because you will divide each number of months by 12 to find the number of years. which would mean, 5, 12.5, 16, 45, 50, 72.5. which is crazy. anyhow, i think you find the median in the middle. and yea hope your test goes good
