At a stadium, there were
37 as many adults as children at first. After 37 adults left, there were 193 more children than adults remaining at a stadium. How many children were at the stadium?
|
Adults |
Children |
Before |
3 u |
7 u |
Change |
- 37 |
|
After |
3 u - 37 |
7 u |
In the end, the number of children was 193 more than the number of adults. If another 193 adults entered the stadium, the number of children and adults would be the same.
7 u = 3 u - 37 + 193
7 u - 3 u = 193 - 37
4 u = 156
1 u = 156 ÷ 4 = 39
Number of children at first
= 7 u
= 7 x 39
= 273
Answer: 273
