Answer to Question #65473 in Electric Circuits for Helen

Question #65473

In The Friendship Contraction episode1 of “The Big Bang Theory,” Penny confirms
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?
