Oscar and Zoe had the same number of sweets. After Zoe gave away 13 sweets and Oscar gave away 49 sweets, Zoe had 2 times as many sweets as Oscar. How many sweets did each of them have at first?
| |
Oscar |
Zoe |
| Before |
1 u + 49 |
2 u + 13 |
| Change |
- 49 |
- 13 |
| After |
1 u |
2 u |
The number of sweets that Oscar and Zoe had at first is the same.
2 u + 13 = 1 u + 49
2 u - 1 u = 49 - 13
1 u = 36
1 u = 36 ÷ 1 = 36
Number of sweets that each of them had at first
= 1 u + 49
= 36 + 49
= 85
Answer(s): 85
