| Before |
6 u |
3 u + 42 |
| Change |
- 5 u |
- 42 |
| After |
1 u |
|
| Comparing between Xuan and Jaslyn in the end |
1 u |
3 u |
Total amount that Xuan and Jaslyn had at first
= 6 u + 3 u + 42
= 9 u + 42
9 u + 42 = 528
6 u + 5 u = 528 - 42
9 u = 486
1 u = 486 ÷ 9 = 54
Amount that Xuan had at first
= 6 u
= 6 x 54
= $324
Amount that Jaslyn had at first
= 528 - 324
= $204
At first
Xuan : Jaslyn
324 : 204
27 : 17
Answer(s): 27 : 17
