|
After |
3 u |
+ 300 |
6x2 =
12 u |
|
200 ÷ 2 = 100
3 x 100 = 300
5 x 100 = 500
Total amount that Vaidev and Cody had at first
= 5 u + 500 + 14 u
= 19 u + 500
19 u + 500 = 1260
19 u = 1260 - 500
19 u = 760
1 u = 760 ÷ 19 = 40
Amount that Vaidev had left
= 3 u + 300
= 3 x 40 + 300
= 120 + 300
= $420
Answer(s): $420
