45If Auntie Xandra baked another 60 strawberry muffins, there would be equal number of vanilla muffins and strawberry muffins in the end.
10 u + 32 = 3 u + 60
10 u - 3 u = 60 - 32
7 u = 28
1 u = 28 ÷ 7 = 4
Total muffins that Auntie Xandra baked
= 15 u + 48 + 15 u
= 30 u + 48
= 30 x 4 + 48
= 120 + 48
= 168
Answer(s): 168
