Mr. mccann is buying lunch and pays $12.90. this includes the cost of his meal and a 20% tip. how much did the meal cost before the tip?

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
