At a stadium, there were
35 as many adults as children at first. After 66 adults left, there were 124 more children than adults remaining at a stadium. How many children were at the stadium?
|
Adults |
Children |
Before |
3 u |
5 u |
Change |
- 66 |
|
After |
3 u - 66 |
5 u |
In the end, the number of children was 124 more than the number of adults. If another 124 adults entered the stadium, the number of children and adults would be the same.
5 u = 3 u - 66 + 124
5 u - 3 u = 124 - 66
2 u = 58
1 u = 58 ÷ 2 = 29
Number of children at first
= 5 u
= 5 x 29
= 145
Answer: 145
