0.6 =
610 =
3537 x 91 = 39
91 - 39 = 52
If Auntie Jade baked another 70 chocolate chip muffins, there would be equal number of vanilla muffins and chocolate chip muffins in the end.
20 u + 52 = 14 u + 70
20 u - 14 u = 70 - 52
6 u = 18
1 u = 18 ÷ 6 = 3
Total muffins that Auntie Jade baked
= 35 u + 91 + 35 u
= 70 u + 91
= 70 x 3 + 91
= 210 + 91
= 301
Answer(s): 301
