Apr. 28
May 46
Jun. 48
Jul. 20
Aug. 48
Sept. 48

To find the median number of maple syrup bottles sold in a month, we first need to arrange the data in ascending order:
21, 20, 28, 46, 48, 48, 48, 72, 96, 110, 111, 115
Since there are 12 months in a year, the median will be the average of the 6th and 7th values in the ordered list:
(48 + 48) / 2 = 48
Therefore, the median number of maple syrup bottles sold in a month is 48.
