0.6 =
610 =
3537 x 84 = 36
84 - 36 = 48
If Auntie Xylia baked another 60 vanilla muffins, there would be equal number of chocolate chip muffins and vanilla muffins in the end.
20 u + 48 = 14 u + 60
20 u - 14 u = 60 - 48
6 u = 12
1 u = 12 ÷ 6 = 2
Total muffins that Auntie Xylia baked
= 35 u + 84 + 35 u
= 70 u + 84
= 70 x 2 + 84
= 140 + 84
= 224
Answer(s): 224
