0.4 =
410 =
2527 x 77 = 22
77 - 22 = 55
If Auntie Gwen baked another 63 blueberry buns, there would be equal number of strawberry buns and blueberry buns in the end.
25 u + 55 = 21 u + 63
25 u - 21 u = 63 - 55
4 u = 8
1 u = 8 ÷ 4 = 2
Total buns that Auntie Gwen baked
= 35 u + 77 + 35 u
= 70 u + 77
= 70 x 2 + 77
= 140 + 77
= 217
Answer(s): 217
