The number of croissants that John had remains unchanged.
If John had another 8 croissants in the end, the number of croissants that Jade and John had would be the same.
3 u - 6 = 1 u + 8
3 u - 1 u = 8 + 6
2 u = 14
1 u = 14 ÷ 2 = 7
Total number of croissants
= 3 u + 1 u
= 4 u
= 4 x 7
= 28
Answer(s): 28
