45If Auntie Gabby baked another 47 apple croissants, there would be equal number of chocolate chip croissants and apple croissants in the end.
5 u + 20 = 2 u + 47
5 u - 2 u = 47 - 20
3 u = 27
1 u = 27 ÷ 3 = 9
Total croissants that Auntie Gabby baked
= 10 u + 40 + 10 u
= 20 u + 40
= 20 x 9 + 40
= 180 + 40
= 220
Answer(s): 220
