45If Auntie Ivory baked another 54 strawberry muffins, there would be equal number of blueberry muffins and strawberry muffins in the end.
15 u + 12 = 8 u + 54
15 u - 8 u = 54 - 12
7 u = 42
1 u = 42 ÷ 7 = 6
Total muffins that Auntie Ivory baked
= 40 u + 32 + 40 u
= 80 u + 32
= 80 x 6 + 32
= 480 + 32
= 512
