Below are 36 sorted ages of an acting award winner. find p80.

20, 22, 22, 24, 25, 28, 28, 29, 29, 30, 34, 35, 35, 36, 37, 39, 44, 48, 49, 51, 51, 51, 54, 56, 57, 58, 63, 66, 67, 72, 72, 74 , 76, 77, 79, 80

P80 = 36 * 0.80 = 28.8

The above equation shows that the 80th percentile will have 28.8 values below it. So obtaining the 29th value will be the 80th percentile. 

Looking at the given values, P80 = 67.

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
