+ 500 |
5 u |

Change 1 |
- 3 u |
- 300 |
+ 3 u |
+ 300 |
After 1 |
2 u |
+ 200 |
8 u |
+ 300 |
Change 2 |
+ 2 u |
+ 75 |
- 2 u |
- 75 |
After 2 |
4 u |
+ 275 |
6 u |
+ 225 |
35 x 500= 300
500 - 300 = 200
25% x 8 u
=
25100 x 8 u
= 2 u
25% x 300
=
25100 x 300
= 75
300 - 75 = 225
200 + 75 = 275
If Opal received another $260 in the end, Opal and Lynn would have the same amount of money.
6 u + 225 = 4 u + 275 + 260
6 u - 4 u = 275 + 260 - 225
2 u = 310
1 u = 310 ÷ 2 = 155
Amount that Lynn had at first
= 5 u
= 5 x 155
= $775
Answer(s): $775
