17 x 14 = 2
14 - 2 = 12

45If Auntie Roshel baked another 150 cheese buns, there would be equal number of apricot buns and cheese buns in the end.
30 u + 12 = 7 u + 150
30 u - 7 u = 150 - 12
23 u = 138
1 u = 138 ÷ 23 = 6
Total buns that Auntie Roshel baked
= 35 u + 14 + 35 u
= 70 u + 14
= 70 x 6 + 14
= 420 + 14
= 434
Answer(s): 434
