At a tourist attraction, there were
47 as many adults as children at first. After 27 adults left, there were 171 more children than adults remaining at a tourist attraction. How many children were at the tourist attraction?
|
Adults |
Children |
Before |
4 u |
7 u |
Change |
- 27 |
|
After |
4 u - 27 |
7 u |
In the end, the number of children was 171 more than the number of adults. If another 171 adults entered the tourist attraction, the number of children and adults would be the same.
7 u = 4 u - 27 + 171
7 u - 4 u = 171 - 27
3 u = 144
1 u = 144 ÷ 3 = 48
Number of children at first
= 7 u
= 7 x 48
= 336
Answer: 336
