|
After |
3 u |
+ 285 |
3x2 =
6 u |
|
190 ÷ 2 = 95
3 x 95 = 285
5 x 95 = 475
Total amount that Vaidev and Oscar had at first
= 5 u + 475 + 8 u
= 13 u + 475
13 u + 475 = 995
13 u = 995 - 475
13 u = 520
1 u = 520 ÷ 13 = 40
Amount that Vaidev had left
= 3 u + 285
= 3 x 40 + 285
= 120 + 285
= $405
Answer(s): $405
