35If Auntie Fiona baked another 172 banana buns, there would be equal number of cranberry buns and banana buns in the end.
35 u + 77 = 16 u + 172
35 u - 16 u = 172 - 77
19 u = 95
1 u = 95 ÷ 19 = 5
Total buns that Auntie Fiona baked
= 40 u + 88 + 40 u
= 80 u + 88
= 80 x 5 + 88
= 400 + 88
= 488
Answer(s): 488
