There were 29 more children in Group W than in Group X. If 10 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 + 29 |
1 u |
|
Change |
- 10 |
+ 10 |
|
After |
1 u + 19 |
1 u + 10 |
|
Number of children that Group W had after transferring to Group X
= 1 u + 29 - 10
= 1 u + 19
Number of children that Group X had after the transfer
= 1 u + 10
Number of children in Group W more than in Group X
= 19 - 10
= 9
