13 x 36 = 12
36 - 12 = 24

45If Auntie Nora baked another 59 chocolate chip buns, there would be equal number of apple buns and chocolate chip buns in the end.
10 u + 24 = 3 u + 59
10 u - 3 u = 59 - 24
7 u = 35
1 u = 35 ÷ 7 = 5
Total buns that Auntie Nora baked
= 15 u + 36 + 15 u
= 30 u + 36
= 30 x 5 + 36
= 150 + 36
= 186
Answer(s): 186
