The fire department has two classes of employees, responders and administrators. The department requires a physical for each new employee, unless that employee has had a physical in the previous year or is an administrator. Last month, the fire department required physicals of 6 new employees. If 3/4 of the new employees are responders, how many new employees does the department have?
(1) 1/6 of the new employees are administrators who have had a physical in the previous year.
(2) 1/3 of the new responders have had a physical in the previous year.
