At a tourist attraction, there were
38 as many adults as children at first. After 45 adults left, there were 200 more children than adults remaining at a tourist attraction. How many adults were at the tourist attraction at first?
| |
Adults |
Children |
| Before |
3 u |
8 u |
| Change |
- 45 |
|
| After |
3 u - 45 |
8 u |
In the end, the number of children was 200 more than the number of adults. If another 200 adults entered the tourist attraction, the number of children and adults would be the same.
8 u = 3 u - 45 + 200
8 u - 3 u = 200 - 45
5 u = 155
1 u = 155 ÷ 5 = 31
Number of adults at first
= 3 u
= 3 x 31
= 93
Answer: 93
