21 - 6 = 15
If Auntie Abi baked another 103 strawberry muffins, there would be equal number of vanilla muffins and strawberry muffins in the end.
25 u + 15 = 14 u + 103
25 u - 14 u = 103 - 15
11 u = 88
1 u = 88 ÷ 11 = 8
Total muffins that Auntie Abi baked
= 35 u + 21 + 35 u
= 70 u + 21
= 70 x 8 + 21
= 560 + 21
= 581
Answer(s): 581
