45If Auntie Ivory baked another 53 strawberry croissants, there would be equal number of chocolate chip croissants and strawberry croissants in the end.
5 u + 29 = 2 u + 53
5 u - 2 u = 53 - 29
3 u = 24
1 u = 24 ÷ 3 = 8
Total croissants that Auntie Ivory baked
= 10 u + 58 + 10 u
= 20 u + 58
= 20 x 8 + 58
= 160 + 58
= 218
Answer(s): 218
