At a safari park, there were
35 as many adults as children at first. After 27 adults left, there were 141 more children than adults remaining at a safari park. How many children were at the safari park?
|
Adults |
Children |
Before |
3 u |
5 u |
Change |
- 27 |
|
After |
3 u - 27 |
5 u |
In the end, the number of children was 141 more than the number of adults. If another 141 adults entered the safari park, the number of children and adults would be the same.
5 u = 3 u - 27 + 141
5 u - 3 u = 141 - 27
2 u = 114
1 u = 114 ÷ 2 = 57
Number of children at first
= 5 u
= 5 x 57
= 285
Answer: 285
