45If Auntie Victoria baked another 70 blueberry buns, there would be equal number of strawberry buns and blueberry buns in the end.
10 u + 28 = 3 u + 70
10 u - 3 u = 70 - 28
7 u = 42
1 u = 42 ÷ 7 = 6
Total buns that Auntie Victoria baked
= 15 u + 42 + 15 u
= 30 u + 42
= 30 x 6 + 42
= 180 + 42
= 222
