Winnie and Anna went shopping with a total of $600. After Winnie spent

4 u |
Total amount that Winnie and Anna had at first
= 5 u + 4 u + 33
= 9 u + 33
9 u + 33 = 600
5 u + 4 u = 600 - 33
9 u = 567
1 u = 567 ÷ 9 = 63
Amount that Winnie had at first
= 5 u
= 5 x 63
= $315
Amount that Anna had at first
= 600 - 315
= $285
At first
Winnie : Anna
315 : 285
21 : 19
Answer(s): 21 : 19
