Transformer with Resistance

A transformer connected to a 120V line is to supply 12 V to a circuit that has a resistance of 2 ohms. 1) If the primary side of the transformer has 1000 turns, how many turns must the secondary side have to achieve this reduction in voltage? 2) Calculate the power into the primary and power output from the secondary.
