0.6 =

3513 x 39 = 13
39 - 13 = 26
If Auntie Kimberly baked another 38 strawberry buns, there would be equal number of cherry buns and strawberry buns in the end.
10 u + 26 = 6 u + 38
10 u - 6 u = 38 - 26
4 u = 12
1 u = 12 ÷ 4 = 3
Total buns that Auntie Kimberly baked
= 15 u + 39 + 15 u
= 30 u + 39
= 30 x 3 + 39
= 90 + 39
= 129
Answer(s): 129
