23 x 54 = 36
54 - 36 = 18

45If Auntie Shannon baked another 28 vanilla buns, there would be equal number of chocolate chip buns and vanilla buns in the end.
5 u + 18 = 3 u + 28
5 u - 3 u = 28 - 18
2 u = 10
1 u = 10 ÷ 2 = 5
Total buns that Auntie Shannon baked
= 15 u + 54 + 15 u
= 30 u + 54
= 30 x 5 + 54
= 150 + 54
= 204
Answer(s): 204
