At a theme park, there were
38 as many adults as children at first. After 37 adults left, there were 192 more children than adults remaining at a theme park. How many adults were at the theme park at first?
|
Adults |
Children |
Before |
3 u |
8 u |
Change |
- 37 |
|
After |
3 u - 37 |
8 u |
In the end, the number of children was 192 more than the number of adults. If another 192 adults entered the theme park, the number of children and adults would be the same.
8 u = 3 u - 37 + 192
8 u - 3 u = 192 - 37
5 u = 155
1 u = 155 ÷ 5 = 31
Number of adults at first
= 3 u
= 3 x 31
= 93
Answer: 93
