Total |
Before |
3 u - $50 |
1 u + $50 |
$328 |
Change |
+ $50 |
- $50 |
|
After |
3 u |
1 u |
$328 |
(a)
Total amount that Vaidev and Ethan have in the end
= 1 u + 3 u
= 4 u
4 u = 328
1 u = 328 ÷ 4 = 82
Amount that Ethan has at first
= 1 u + 50
= 82 + 50
= $132
(b)
Amount that Vaidev has at first
= 328 - 132
= $196
Answer(s): (a) $132; (b) $196
