If Auntie Nicole baked another 28 cranberry croissants, there would be equal number of banana croissants and cranberry croissants in the end.
5 u + 10 = 3 u + 28
5 u - 3 u = 28 - 10
2 u = 18
1 u = 18 ÷ 2 = 9
Total croissants that Auntie Nicole baked
= 15 u + 30 + 15 u
= 30 u + 30
= 30 x 9 + 30
= 270 + 30
= 300
Answer(s): 300
