Respuesta :

Answer:

180

Step-by-step explanation:

Let the number of research assistants employed be y

Given that there are two times as many teaching assistants as research assistants, then

Number of teaching assistants = 2y

Since there are 540 employed

y + 2y = 540

3y = 540

y = 540/3

y = 180

There are 180 research assistants employed by the university.
