Raeann had 20 more croissants than Kylie at first. After Raeann ate 6 croissants, she had thrice as many croissants as Kylie in the end. How many croissants did Kylie have?

Raeann |
| Before |
1 u |
1 u + 20 |
| Change |
|
- 6 |
| After |
1 u |
1 u + 14 |
Comparing Kylie
and Raeann in the end |
1 u |
3 u |
The number of croissants that Kylie had remains unchanged.
Number of croissants that Raeann had in the end
= 3 x 1 u
= 3 u
3 u = 1 u + 14
3 u - 1 u = 14
2 u = 14
1 u = 14 ÷ 2 = 7
Number of croissants that Kylie had
= 1 u
= 7
Answer(s): 7
