45If Auntie Vanessa baked another 132 cheese muffins, there would be equal number of chocolate chip muffins and cheese muffins in the end.
25 u + 75 = 6 u + 132
25 u - 6 u = 132 - 75
19 u = 57
1 u = 57 ÷ 19 = 3
Total muffins that Auntie Vanessa baked
= 30 u + 90 + 30 u
= 60 u + 90
= 60 x 3 + 90
= 180 + 90
= 270
Answer(s): 270
