0.6 =

3514 x 72 = 18
72 - 18 = 54
If Auntie Raeann baked another 89 strawberry buns, there would be equal number of chocolate chip buns and strawberry buns in the end.
15 u + 54 = 8 u + 89
15 u - 8 u = 89 - 54
7 u = 35
1 u = 35 ÷ 7 = 5
Total buns that Auntie Raeann baked
= 20 u + 72 + 20 u
= 40 u + 72
= 40 x 5 + 72
= 200 + 72
= 272
Answer(s): 272
