Final answer:
The total number of lockers in the dressing room is equal to the number of players plus three.
Step-by-step explanation:
In order to find the total number of lockers in the dressing room, we need to know the number of players. Let's assume there are 'x' players.
According to the given information, there are 3 more lockers than players. So the total number of lockers would be 'x + 3'.
Therefore, the total number of lockers in the dressing room is 'x + 3'.
