45If Auntie Opal baked another 169 strawberry buns, there would be equal number of cranberry buns and strawberry buns in the end.
25 u + 25 = 7 u + 169
25 u - 7 u = 169 - 25
18 u = 144
1 u = 144 ÷ 18 = 8
Total buns that Auntie Opal baked
= 35 u + 35 + 35 u
= 70 u + 35
= 70 x 8 + 35
= 560 + 35
= 595
Answer(s): 595
