Calculate the period of Procyon B's revolution about Procyon A in years.

What info do I need to get first? What kind of equations will I be using to solve this?

It's been a long time since I've done physics. I believe that Newton's law of universal gravitation would be helpful along with
knowing the distance and masses involved.

... some given orbital data and Kepler's 3rd law of planetary motion.
