September Mathematics Challenge

Students,

The following problem will be here for the the entire month.  In my classroom, there will be a P.O.M (Problem of the Month) Box along with a template for how I would like to see the problem written up for your submission.  You can only make you submission.  At the end of the month, I will select two students's solutions from the box who were correct.  If I have to draw twenty from the box until I find two correct answers I will.  Those two students who have the correct answers will receive a $10.00 Subway gift card.

Good luck,

Mr. Giomini

The Banjoff family bought a $120 thermostat that reduces the temperature setting at night, the family hopes to cut its annual heating bill by 8%, and thereby recover the cost of the thermostat in fuel savings after 2 years.  What was the family's annual fuel bill before installing the thermostat?
