Justin |
Ken |
More |
| Before |
8 u + $50.50 |
8 u |
$50.50 |
| Change |
|
- 3 u |
|
| After |
8 u + $50.50 |
5 u |
3 u + $50.50 |
Justin had $96.10 more than Ken in the end.
8 u + 50.50 - 5 u = 96.10
3 u + 50.50 = 96.10
3 u = 96.10 - 50.50
3 u = 45.60
1 u = 45.60 ÷ 3 = 15.20
Amount that Justin had at first
= 8 u + 50.50
= 8 x 15.20 + 50.50
= 121.60 + 50.50
= $172.10
Answer(s): $172.10
