24 - 6 = 18
If Auntie Ivory baked another 74 chocolate chip muffins, there would be equal number of banana muffins and chocolate chip muffins in the end.
15 u + 18 = 8 u + 74
15 u - 8 u = 74 - 18
7 u = 56
1 u = 56 ÷ 7 = 8
Total muffins that Auntie Ivory baked
= 20 u + 24 + 20 u
= 40 u + 24
= 40 x 8 + 24
= 320 + 24
= 344
Answer(s): 344
