2 u - $47 |
1 u + $47 |
$225 |
Change |
+ $47 |
- $47 |
|
After |
2 u |
1 u |
$225 |
(a)
Total amount that Cody and Fred have in the end
= 1 u + 2 u
= 3 u
3 u = 225
1 u = 225 ÷ 3 = 75
Amount that Fred has at first
= 1 u + 47
= 75 + 47
= $122
(b)
Amount that Cody has at first
= 225 - 122
= $103
Answer(s): (a) $122; (b) $103
