4537 x 28 = 12
28 - 12 = 16
If Auntie Anna baked another 42 vanilla muffins, there would be equal number of strawberry muffins and vanilla muffins in the end.
20 u + 16 = 7 u + 42
20 u - 7 u = 42 - 16
13 u = 26
1 u = 26 ÷ 13 = 2
Total muffins that Auntie Anna baked
= 35 u + 28 + 35 u
= 70 u + 28
= 70 x 2 + 28
= 140 + 28
= 168
Answer(s): 168
