There were 25 more children in Group W than in Group X. If 9 children transferred from Group W to Group X, how many more children would be in Group W than in Group X?
|
Group W |
Group X |
|
Before |
1 u + 25 |
1 u |
|
Change |
- 9 |
+ 9 |
|
After |
1 u + 16 |
1 u + 9 |
|
Number of children that Group W had after transferring to Group X
= 1 u + 25 - 9
= 1 u + 16
Number of children that Group X had after the transfer
= 1 u + 9
Number of children in Group W more than in Group X
= 16 - 9
= 7
Answer(s): 7
