Opal and Linda went shopping with a total of $775. After Opal spent

- 4 u |
- 95 |
| After |

| Comparing between Opal and Linda in the end |
1 u |
3 u |
Total amount that Opal and Linda had at first
= 5 u + 3 u + 95
= 8 u + 95
8 u + 95 = 775
5 u + 4 u = 775 - 95
8 u = 680
1 u = 680 ÷ 8 = 85
Amount that Opal had at first
= 5 u
= 5 x 85
= $425
Amount that Linda had at first
= 775 - 425
= $350
At first
Opal : Linda
425 : 350
17 : 14
Answer(s): 17 : 14
