At a museum, there were
37 as many adults as children at first. After 32 adults left, there were 184 more children than adults remaining at a museum. How many children were at the museum?
|
Adults |
Children |
Before |
3 u |
7 u |
Change |
- 32 |
|
After |
3 u - 32 |
7 u |
In the end, the number of children was 184 more than the number of adults. If another 184 adults entered the museum, the number of children and adults would be the same.
7 u = 3 u - 32 + 184
7 u - 3 u = 184 - 32
4 u = 152
1 u = 152 ÷ 4 = 38
Number of children at first
= 7 u
= 7 x 38
= 266
Answer: 266
