At a tourist attraction, there were
47 as many adults as children at first. After 43 adults left, there were 136 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 |
- 43 |
|
After |
4 u - 43 |
7 u |
In the end, the number of children was 136 more than the number of adults. If another 136 adults entered the tourist attraction, the number of children and adults would be the same.
7 u = 4 u - 43 + 136
7 u - 4 u = 136 - 43
3 u = 93
1 u = 93 ÷ 3 = 31
Number of children at first
= 7 u
= 7 x 31
= 217
Answer: 217
