At a safari park, there were
35 as many adults as children at first. After 68 adults left, there were 114 more children than adults remaining at a safari park. How many adults were at the safari park at first?
| |
Adults |
Children |
| Before |
3 u |
5 u |
| Change |
- 68 |
|
| After |
3 u - 68 |
5 u |
In the end, the number of children was 114 more than the number of adults. If another 114 adults entered the safari park, the number of children and adults would be the same.
5 u = 3 u - 68 + 114
5 u - 3 u = 114 - 68
2 u = 46
1 u = 46 ÷ 2 = 23
Number of adults at first
= 3 u
= 3 x 23
= 69
Answer: 69
