45If Auntie Tiffany baked another 126 strawberry muffins, there would be equal number of vanilla muffins and strawberry muffins in the end.
15 u + 60 = 4 u + 126
15 u - 4 u = 126 - 60
11 u = 66
1 u = 66 ÷ 11 = 6
Total muffins that Auntie Tiffany baked
= 20 u + 80 + 20 u
= 40 u + 80
= 40 x 6 + 80
= 240 + 80
= 320
Answer(s): 320
