At a theme park, there were
47 as many adults as children at first. After 35 adults left, there were 176 more children than adults remaining at a theme park. How many adults were at the theme park at first?
|
Adults |
Children |
Before |
4 u |
7 u |
Change |
- 35 |
|
After |
4 u - 35 |
7 u |
In the end, the number of children was 176 more than the number of adults. If another 176 adults entered the theme park, the number of children and adults would be the same.
7 u = 4 u - 35 + 176
7 u - 4 u = 176 - 35
3 u = 141
1 u = 141 ÷ 3 = 47
Number of adults at first
= 4 u
= 4 x 47
= 188
Answer: 188
