|
After |
3 u |
+ 324 |
6x2 =
12 u |
|
216 ÷ 2 = 108
3 x 108 = 324
5 x 108 = 540
Total amount that Seth and Bobby had at first
= 5 u + 540 + 14 u
= 19 u + 540
19 u + 540 = 1262
19 u = 1262 - 540
19 u = 722
1 u = 722 ÷ 19 = 38
Amount that Seth had at first
= 5 u + 540
= 5 x 38 + 540
= 190 + 540
= $730
Answer(s): $730
