3 u |
Total amount that Cindy and Yoko had at first
= 4 u + 3 u + 40
= 7 u + 40
7 u + 40 = 656
4 u + 3 u = 656 - 40
7 u = 616
1 u = 616 ÷ 7 = 88
Amount that Cindy had at first
= 4 u
= 4 x 88
= $352
Amount that Yoko had at first
= 656 - 352
= $304
At first
Cindy : Yoko
352 : 304
22 : 19
Answer(s): 22 : 19
