At a safari park, there were
37 as many adults as children at first. After 23 adults left, there were 183 more children than adults remaining at a safari park. How many adults were at the safari park at first?
| |
Adults |
Children |
| Before |
3 u |
7 u |
| Change |
- 23 |
|
| After |
3 u - 23 |
7 u |
In the end, the number of children was 183 more than the number of adults. If another 183 adults entered the safari park, the number of children and adults would be the same.
7 u = 3 u - 23 + 183
7 u - 3 u = 183 - 23
4 u = 160
1 u = 160 ÷ 4 = 40
Number of adults at first
= 3 u
= 3 x 40
= 120
Answer: 120
