45If Auntie Zara baked another 49 apple croissants, there would be equal number of blueberry croissants and apple croissants in the end.
5 u + 31 = 3 u + 49
5 u - 3 u = 49 - 31
2 u = 18
1 u = 18 ÷ 2 = 9
Total croissants that Auntie Zara baked
= 15 u + 93 + 15 u
= 30 u + 93
= 30 x 9 + 93
= 270 + 93
= 363
Answer(s): 363
