A research facility employs a total of 540 research staff and laboratory assistants. Research staff are paid $240 per day and laboratory assistants are paid $200 a day. Given that the total wage bill per day is $120 000, find the number of research staff and the number of laboratory assistants employed by the facility.

Let the number of research staff =R
Let the number of Lab assistants=A
R + A = 540
240R + 200A =120,000 solve for A, R
A = 240 - Number of Lab assistants.
R = 300 - Number of reaserchers.
