At a tourist attraction, there were
35 as many adults as children at first. After 72 adults left, there were 176 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 |
- 72 |
|
After |
3 u - 72 |
5 u |
In the end, the number of children was 176 more than the number of adults. If another 176 adults entered the tourist attraction, the number of children and adults would be the same.
5 u = 3 u - 72 + 176
5 u - 3 u = 176 - 72
2 u = 104
1 u = 104 ÷ 2 = 52
Number of adults at first
= 3 u
= 3 x 52
= 156
Answer: 156
