Since both of them can fit the people evenly into rows, when you divide the number of people by the rows, you should get a whole number. For The Children's Theater, there are 25 people in each row. (1575/63)
For the Bartell Theater, there are 32 people seated in each row.(2048/64)
Now, all you have to do is find the difference between them. 32 minus 25 is 7.
You final answer will be: There are 7 more people seated at the Bartell Theater than The Children's Theater.
