A manager at a shopping mall counts 244 males and n females as they enter the mall. The manager realizes that 25% of all males and 25% of all females are children. She writes the expression 0.25n + 61 to represent the number of children who enter the mall. Is the manager correct?

No, the manager is not correct. The expression 0.25n + 61 represents only the number of children who are females, not the total number of children. To represent the total number of children who enter the mall, the correct expression would be 0.25(244 + n).
