David had
16 as much money as Christian at first. After David received $168 and Christian received $88, both of them had the same amount of money. How much did Christian have at first?
|
David |
Christian |
Before |
1 u |
6 u |
Change |
+ 168 |
+ 88 |
After |
1 u + 168 |
6 u + 88 |
The amount that David and Christian had in the end is the same.
1 u + 168 = 6 u + 88
6 u - 1 u = 168 - 88 = 80
5 u = 80
1 u = 80 ÷ 5 = 16
Amount that Christian had at first
= 6 u
= 6 x 16
= $96
Answer(s): $96
