A 120 V circuit in a house is equipped with a 20 A circuit breaker that will "trip" (i.e., shut off) if the current exceeds 20 A. How many 742 watt appliances can be plugged into the sockets of that circuit before the circuit breaker trips? (Note that the answer is a whole number as fractional appliances are not possible!),
