| Comparing between Victoria and Eva in the end |
1 u |
3 u |
Total amount that Victoria and Eva had at first
= 5 u + 3 u + 75
= 8 u + 75
8 u + 75 = 435
5 u + 4 u = 435 - 75
8 u = 360
1 u = 360 ÷ 8 = 45
Amount that Victoria had at first
= 5 u
= 5 x 45
= $225
Amount that Eva had at first
= 435 - 225
= $210
At first
Victoria : Eva
225 : 210
15 : 14
Answer(s): 15 : 14
