0.8 =

4523 x 75 = 50
75 - 50 = 25
If Auntie Gillian baked another 35 cheese croissants, there would be equal number of banana croissants and cheese croissants in the end.
5 u + 25 = 3 u + 35
5 u - 3 u = 35 - 25
2 u = 10
1 u = 10 ÷ 2 = 5
Total croissants that Auntie Gillian baked
= 15 u + 75 + 15 u
= 30 u + 75
= 30 x 5 + 75
= 150 + 75
= 225
Answer(s): 225
