power factor correction question!

A 1,000W electric motor is connected to a source of 120V rms, 60 Hz, and the result is a lagging power factor of 0.8 (+0.8). To correct the pf to a 0.95 lagging, a capacitor is placed in aprallel with the motor. Calculate the current drawn from the source with and without the capacitor connected. Determine the value of the capacitor required to make the correction.

I have no idea where to start or how to start.. any help ?
