At a theme park, there were
37 as many adults as children at first. After 46 adults left, there were 190 more children than adults remaining at a theme park. How many children were at the theme park?
| |
Adults |
Children |
| Before |
3 u |
7 u |
| Change |
- 46 |
|
| After |
3 u - 46 |
7 u |
In the end, the number of children was 190 more than the number of adults. If another 190 adults entered the theme park, the number of children and adults would be the same.
7 u = 3 u - 46 + 190
7 u - 3 u = 190 - 46
4 u = 144
1 u = 144 ÷ 4 = 36
Number of children at first
= 7 u
= 7 x 36
= 252
Answer: 252
