At a safari park, there were
47 as many adults as children at first. After 59 adults left, there were 137 more children than adults remaining at a safari park. How many adults were at the safari park at first?
|
Adults |
Children |
Before |
4 u |
7 u |
Change |
- 59 |
|
After |
4 u - 59 |
7 u |
In the end, the number of children was 137 more than the number of adults. If another 137 adults entered the safari park, the number of children and adults would be the same.
7 u = 4 u - 59 + 137
7 u - 4 u = 137 - 59
3 u = 78
1 u = 78 ÷ 3 = 26
Number of adults at first
= 4 u
= 4 x 26
= 104
Answer: 104
