At a tourist attraction, there were
35 as many adults as children at first. After 49 adults left, there were 125 more children than adults remaining at a tourist attraction. How many adults were at the tourist attraction at first?
|
Adults |
Children |
Before |
3 u |
5 u |
Change |
- 49 |
|
After |
3 u - 49 |
5 u |
In the end, the number of children was 125 more than the number of adults. If another 125 adults entered the tourist attraction, the number of children and adults would be the same.
5 u = 3 u - 49 + 125
5 u - 3 u = 125 - 49
2 u = 76
1 u = 76 ÷ 2 = 38
Number of adults at first
= 3 u
= 3 x 38
= 114
Answer: 114
