35If Auntie Opal baked another 78 chocolate chip croissants, there would be equal number of cherry croissants and chocolate chip croissants in the end.
10 u + 46 = 6 u + 78
10 u - 6 u = 78 - 46
4 u = 32
1 u = 32 ÷ 4 = 8
Total croissants that Auntie Opal baked
= 15 u + 69 + 15 u
= 30 u + 69
= 30 x 8 + 69
= 240 + 69
= 309
Answer(s): 309
