Total |
Before |
4 u - $12 |
1 u + $12 |
$205 |
Change |
+ $12 |
- $12 |
|
After |
4 u |
1 u |
$205 |
(a)
Total amount that Mark and Valen have in the end
= 1 u + 4 u
= 5 u
5 u = 205
1 u = 205 ÷ 5 = 41
Amount that Valen has at first
= 1 u + 12
= 41 + 12
= $53
(b)
Amount that Mark has at first
= 205 - 53
= $152
Answer(s): (a) $53; (b) $152
