[College Physics] Refrigerator (Heat-Engines) HomeworkHelp

A refrigerator uses 100 W of power to remove 100 kJ of heat per minute from the 2 degrees celsius interor. According to the makers of the refrigerator, this claim is true in a 22 degrees celsius kitchen. Should one buy this refrigerator?

I know Qh=Qc+W(in). Also, the 100 W = 100 J/s but I don't know where to go from here. I don't know where to include power in refrigerator problems.
