Answer to Question #65355 in Electric Circuits for Helen
with Sheldon and Leonard that the power has gone out. She had been concerned
because last month she “sent the electric company a Starbucks gift card, an apology
note,” and a few pictures. If the cost of electricity was $0.17 per kWh and the Starbucks
gift card had a value of $10 (and we don’t consider the value of the pictures), for how
many hours could Penny have left her TV on if the TV requires 50.0 watts of power?
