15If Auntie Gwen baked another 28 chocolate chip croissants, there would be equal number of blueberry croissants and chocolate chip croissants in the end.
30 u + 24 = 28 u + 28
30 u - 28 u = 28 - 24
2 u = 4
1 u = 4 ÷ 2 = 2
Total croissants that Auntie Gwen baked
= 35 u + 28 + 35 u
= 70 u + 28
= 70 x 2 + 28
= 140 + 28
= 168
Answer(s): 168
