0.8 =

4512 x 98 = 49
98 - 49 = 49
If Auntie Tiffany baked another 61 banana buns, there would be equal number of strawberry buns and banana buns in the end.
5 u + 49 = 2 u + 61
5 u - 2 u = 61 - 49
3 u = 12
1 u = 12 ÷ 3 = 4
Total buns that Auntie Tiffany baked
= 10 u + 98 + 10 u
= 20 u + 98
= 20 x 4 + 98
= 80 + 98
= 178
Answer(s): 178
