Which inequality represents the following statement A number increased by 4 is at the most 15?

The statement "A number increased by 4 is at the most 15" can be represented by the inequality ( x + 4 \leq 15 ), where ( x ) is the number in question. This means that when 4 is added to ( x ), the result should not exceed 15. To isolate ( x ), you can subtract 4 from both sides, leading to ( x \leq 11 ).
