0.4 =
410 =
2527 x 91 = 26
91 - 26 = 65
If Auntie Emma baked another 81 cherry buns, there would be equal number of banana buns and cherry buns in the end.
25 u + 65 = 21 u + 81
25 u - 21 u = 81 - 65
4 u = 16
1 u = 16 ÷ 4 = 4
Total buns that Auntie Emma baked
= 35 u + 91 + 35 u
= 70 u + 91
= 70 x 4 + 91
= 280 + 91
= 371
Answer(s): 371
