0.8 =

4513 x 66 = 22
66 - 22 = 44
If Auntie Rachel baked another 58 cranberry buns, there would be equal number of apple buns and cranberry buns in the end.
10 u + 44 = 3 u + 58
10 u - 3 u = 58 - 44
7 u = 14
1 u = 14 ÷ 7 = 2
Total buns that Auntie Rachel baked
= 15 u + 66 + 15 u
= 30 u + 66
= 30 x 2 + 66
= 60 + 66
= 126
Answer(s): 126
