Luke and Roshel had the same number of sweets. After Roshel gave away 18 sweets and Luke gave away 48 sweets, Roshel had 2 times as many sweets as Luke. How many sweets did each of them have at first?
| |
Luke |
Roshel |
| Before |
1 u + 48 |
2 u + 18 |
| Change |
- 48 |
- 18 |
| After |
1 u |
2 u |
The number of sweets that Luke and Roshel had at first is the same.
2 u + 18 = 1 u + 48
2 u - 1 u = 48 - 18
1 u = 30
1 u = 30 ÷ 1 = 30
Number of sweets that each of them had at first
= 1 u + 48
= 30 + 48
= 78
Answer(s): 78
