At a safari park, there were
37 as many adults as children at first. After 69 adults left, there were 157 more children than adults remaining at a safari park. How many children were at the safari park?
|
Adults |
Children |
Before |
3 u |
7 u |
Change |
- 69 |
|
After |
3 u - 69 |
7 u |
In the end, the number of children was 157 more than the number of adults. If another 157 adults entered the safari park, the number of children and adults would be the same.
7 u = 3 u - 69 + 157
7 u - 3 u = 157 - 69
4 u = 88
1 u = 88 ÷ 4 = 22
Number of children at first
= 7 u
= 7 x 22
= 154
Answer: 154
