0.8 =
810 =
4513 x 36 = 12
36 - 12 = 24
If Auntie Gwen baked another 87 apple buns, there would be equal number of cherry buns and apple buns in the end.
10 u + 24 = 3 u + 87
10 u - 3 u = 87 - 24
7 u = 63
1 u = 63 ÷ 7 = 9
Total buns that Auntie Gwen baked
= 15 u + 36 + 15 u
= 30 u + 36
= 30 x 9 + 36
= 270 + 36
= 306
Answer(s): 306
