25If Auntie Hilda baked another 18 vanilla buns, there would be equal number of blueberry buns and vanilla buns in the end.
15 u + 12 = 12 u + 18
15 u - 12 u = 18 - 12
3 u = 6
1 u = 6 ÷ 3 = 2
Total buns that Auntie Hilda baked
= 20 u + 16 + 20 u
= 40 u + 16
= 40 x 2 + 16
= 80 + 16
= 96
Answer(s): 96
