4 u |
Total amount that Yen and Kimberly had at first
= 4 u + 4 u + 24
= 8 u + 24
8 u + 24 = 336
4 u + 3 u = 336 - 24
8 u = 312
1 u = 312 ÷ 8 = 39
Amount that Yen had at first
= 4 u
= 4 x 39
= $156
Amount that Kimberly had at first
= 336 - 156
= $180
At first
Yen : Kimberly
156 : 180
13 : 15
Answer(s): 13 : 15
