3 u |
Total amount that Marion and Jane had at first
= 5 u + 3 u + 70
= 8 u + 70
8 u + 70 = 238
5 u + 4 u = 238 - 70
8 u = 168
1 u = 168 ÷ 8 = 21
Amount that Marion had at first
= 5 u
= 5 x 21
= $105
Amount that Jane had at first
= 238 - 105
= $133
At first
Marion : Jane
105 : 133
15 : 19
Answer(s): 15 : 19
