Luke and Fred went shopping with the same amount of money. After Luke spent $85 and Fred spent $81, Fred had three times as much money left as Luke. How much money did each of them bring along for shopping?
| |
Luke |
Fred |
| Before |
1 u + $85 |
3 u + $81 |
| Change |
- $85 |
- $81 |
| After |
1 u |
3 u |
Luke and Fred brought the same amount for shopping at first.
3 u + 81 = 1 u + 85
3 u - 1 u = 85 - 81
2 u = 4
1 u = 4 ÷ 2 = 2
Amount that each of them brought along for shopping
= 1 u + 85
= 2 + 85
= $87
Answer(s): $87
