40

To find the difference between the highest paid and lowest paid managers, you need to subtract the salary of the lowest paid manager from the salary of the highest paid manager.

First, let's list the salaries of the managers in ascending order: 50, 60, 70, 80, 90.

The lowest paid manager earns $50, and the highest paid manager earns $90.

To calculate the difference, subtract the lowest salary from the highest salary: $90 - $50 = $40.

Therefore, the difference between the highest paid and lowest paid managers is $40,000.
