Before |
3 u - $15 |
1 u + $15 |
$276 |
Change |
+ $15 |
- $15 |
|
After |
3 u |
1 u |
$276 |
(a)
Total amount that Simon and Daniel have in the end
= 1 u + 3 u
= 4 u
4 u = 276
1 u = 276 ÷ 4 = 69
Amount that Daniel has at first
= 1 u + 15
= 69 + 15
= $84
(b)
Amount that Simon has at first
= 276 - 84
= $192
Answer(s): (a) $84; (b) $192
