Which of the following could be the first step in solving this problem? 9(12-3)+4

Using P.E.M.D.A.S. ( parentheses exponent multiply divide add subtract ) you would multiply the nine into the parentheses

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
