0.8 =
810 =
4523 x 78 = 52
78 - 52 = 26
If Auntie Kathy baked another 34 strawberry buns, there would be equal number of cranberry buns and strawberry buns in the end.
5 u + 26 = 3 u + 34
5 u - 3 u = 34 - 26
2 u = 8
1 u = 8 ÷ 2 = 4
Total buns that Auntie Kathy baked
= 15 u + 78 + 15 u
= 30 u + 78
= 30 x 4 + 78
= 120 + 78
= 198
Answer(s): 198
