36 - 12 = 24
If Auntie Zoe baked another 38 blueberry muffins, there would be equal number of banana muffins and blueberry muffins in the end.
10 u + 24 = 3 u + 38
10 u - 3 u = 38 - 24
7 u = 14
1 u = 14 ÷ 7 = 2
Total muffins that Auntie Zoe baked
= 15 u + 36 + 15 u
= 30 u + 36
= 30 x 2 + 36
= 60 + 36
= 96
Answer(s): 96
