Total |
Before |
4 u - $25 |
1 u + $25 |
$355 |
Change |
+ $25 |
- $25 |
|
After |
4 u |
1 u |
$355 |
(a)
Total amount that Peter and Ahmad have in the end
= 1 u + 4 u
= 5 u
5 u = 355
1 u = 355 ÷ 5 = 71
Amount that Ahmad has at first
= 1 u + 25
= 71 + 25
= $96
(b)
Amount that Peter has at first
= 355 - 96
= $259
Answer(s): (a) $96; (b) $259
