25If Auntie Tiffany baked another 28 vanilla buns, there would be equal number of blueberry buns and vanilla buns in the end.
25 u + 20 = 21 u + 28
25 u - 21 u = 28 - 20
4 u = 8
1 u = 8 ÷ 4 = 2
Total buns that Auntie Tiffany baked
= 35 u + 28 + 35 u
= 70 u + 28
= 70 x 2 + 28
= 140 + 28
= 168
Answer(s): 168
