15If Auntie Hazel baked another 22 cherry muffins, there would be equal number of banana muffins and cherry muffins in the end.
30 u + 18 = 28 u + 22
30 u - 28 u = 22 - 18
2 u = 4
1 u = 4 ÷ 2 = 2
Total muffins that Auntie Hazel baked
= 35 u + 21 + 35 u
= 70 u + 21
= 70 x 2 + 21
= 140 + 21
= 161
Answer(s): 161
