Oliver and Yoko had the same number of sweets. After Yoko gave away 13 sweets and Oliver gave away 53 sweets, Yoko had 2 times as many sweets as Oliver. How many sweets did each of them have at first?
| |
Oliver |
Yoko |
| Before |
1 u + 53 |
2 u + 13 |
| Change |
- 53 |
- 13 |
| After |
1 u |
2 u |
The number of sweets that Oliver and Yoko had at first is the same.
2 u + 13 = 1 u + 53
2 u - 1 u = 53 - 13
1 u = 40
1 u = 40 ÷ 1 = 40
Number of sweets that each of them had at first
= 1 u + 53
= 40 + 53
= 93
Answer(s): 93
