Before |
3 u - $10 |
1 u + $10 |
$264 |
Change |
+ $10 |
- $10 |
|
After |
3 u |
1 u |
$264 |
(a)
Total amount that Tommy and Tim have in the end
= 1 u + 3 u
= 4 u
4 u = 264
1 u = 264 ÷ 4 = 66
Amount that Tim has at first
= 1 u + 10
= 66 + 10
= $76
(b)
Amount that Tommy has at first
= 264 - 76
= $188
Answer(s): (a) $76; (b) $188
