2 u - $19 |
1 u + $19 |
$114 |
Change |
+ $19 |
- $19 |

After |
2 u |
1 u |
$114 |
(a)
Total amount that Andy and Simon have in the end
= 1 u + 2 u
= 3 u
3 u = 114
1 u = 114 ÷ 3 = 38
Amount that Simon has at first
= 1 u + 19
= 38 + 19
= $57
(b)
Amount that Andy has at first
= 114 - 57
= $57
Answer(s): (a) $57; (b) $57
