A 50mV signal is applied to the base of a properly biased transistor with r'e=10ohms and RC=560ohms. Determine the signal voltage at the collector.

In my text book for this section there are formulas
Vb=Ier'e
Vc=IcRC
Vc=IeRC

Do I take 50mV/560ohms to get Ic then take that result and multiply by 560ohms to get VC? Not sure where the r'e=10ohms comes into play.
Any help would be much appreciated.
