Pierre Moran has 679 students. For every 4 hybrid students there are 3 virtual only students. How many virtual only students does Pierre Moran have?A. 388B. 207C. 291D. None of the above

Answer 1

`\begin{gathered} h+v=679\Rightarrow(1) \\ 4h=3v \\ h=(3v)/(4)\Rightarrow(2) \\ \text{Now, from equation (1) and (2).} \\ (3v)/(4)+v=679 \\ (3v+4v)/(4)=679 \\ 7v=679*4 \\ v=388 \\ \text{Thus, the virtual students is 388.} \end{gathered}`
