Total |
Before |
2 u - $15 |
1 u + $15 |
$174 |
Change |
+ $15 |
- $15 |
|
After |
2 u |
1 u |
$174 |
(a)
Total amount that George and Glen have in the end
= 1 u + 2 u
= 3 u
3 u = 174
1 u = 174 ÷ 3 = 58
Amount that Glen has at first
= 1 u + 15
= 58 + 15
= $73
(b)
Amount that George has at first
= 174 - 73
= $101
Answer(s): (a) $73; (b) $101
