Do you know the answer?

Below is another video clip from a Jeffers Pond 5th grade classroom earlier this week. The question is how much money would be saved in electrical costs if 10,000 schools turned off their lights for just one minute?

The four possible answers are:
A) It costs more to turn the lights off than leave them on.
B) $81,900
C) $5,000
D) One minute is not enough time to make a difference.

Watch the video clip to see if you chose the correct answer and pay close attention because the contestant chooses the 50/50 lifeline so the computer takes away two wrong answers.
