Comparing between Anna and Nicole in the end |
1 u |
3 u |
Total amount that Anna and Nicole had at first
= 5 u + 3 u + 36
= 8 u + 36
8 u + 36 = 228
5 u + 4 u = 228 - 36
8 u = 192
1 u = 192 ÷ 8 = 24
Amount that Anna had at first
= 5 u
= 5 x 24
= $120
Amount that Nicole had at first
= 228 - 120
= $108
At first
Anna : Nicole
120 : 108
10 : 9
Answer(s): 10 : 9
