|
After |
5 u |
+ 215 |
4x3 =
12 u |
|
129 ÷ 3 = 43
5 x 43 = 215
8 x 43 = 344
Total amount that Jenson and Vaidev had at first
= 8 u + 344 + 15 u
= 23 u + 344
23 u + 344 = 1034
23 u = 1034 - 344
23 u = 690
1 u = 690 ÷ 23 = 30
Amount that Jenson had at first
= 8 u + 344
= 8 x 30 + 344
= 240 + 344
= $584
Answer(s): $584
