35If Auntie Natalie baked another 78 strawberry croissants, there would be equal number of blueberry croissants and strawberry croissants in the end.
10 u + 66 = 6 u + 78
10 u - 6 u = 78 - 66
4 u = 12
1 u = 12 ÷ 4 = 3
Total croissants that Auntie Natalie baked
= 15 u + 99 + 15 u
= 30 u + 99
= 30 x 3 + 99
= 90 + 99
= 189
Answer(s): 189
