At a museum, there were
35 as many adults as children at first. After 37 adults left, there were 173 more children than adults remaining at a museum. How many children were at the museum?
|
Adults |
Children |
Before |
3 u |
5 u |
Change |
- 37 |
|
After |
3 u - 37 |
5 u |
In the end, the number of children was 173 more than the number of adults. If another 173 adults entered the museum, the number of children and adults would be the same.
5 u = 3 u - 37 + 173
5 u - 3 u = 173 - 37
2 u = 136
1 u = 136 ÷ 2 = 68
Number of children at first
= 5 u
= 5 x 68
= 340
Answer: 340
