Students are selling muffins at a school bake sale. One muffin costs $0.22, 2 muffins cost $0.33, 3 muffins cost $0.44, and 4 muffins cost $0.55. Since each additional muffin costs $0.11, how much will 7 muffins cost??

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
