Comparing Xandra and Roshel at first |
480 more |

Before |
5 u |
+ 480 |
5 u |
|
Change 1 |
- 3 u |
- 288 |
+ 3 u |
+ 288 |
After 1 |
2 u |
+ 192 |
8 u |
+ 288 |
Change 2 |
+ 2 u |
+ 72 |
- 2 u |
- 72 |
After 2 |
4 u |
+ 264 |
6 u |
+ 216 |
35 x 480= 288
480 - 288 = 192
25% x 8 u
=
25100 x 8 u
= 2 u
25% x 288
=
25100 x 288
= 72
288 - 72 = 216
192 + 72 = 264
If Xandra received another $288 in the end, Xandra and Roshel would have the same amount of money.
6 u + 216 = 4 u + 264 + 288
6 u - 4 u = 264 + 288 - 216
2 u = 336
1 u = 336 ÷ 2 = 168
Amount that Xandra had at first
= 5 u + 480
= 5 x 168 + 480
= 840 + 480
= $1320
Answer(s): $1320
