Quantitative Reasoning Program Choosing Between Home Appliances:
Benefits to the Planet and Your Wallet part of SISL:2012
Sustainability in Math Workshop:Activities In this activity,
students compare various options for purchasing new home
appliances: refrigerators, washing machines, clothes dryers,
dishwashers, microwave ovens, electric ranges, and window air
conditioning units. Students compare the energy usage of more
efficient models to less energy efficient models, and calculate
the "payback period" in cases for which the purchase price for
the energy efficient model is higher, but the energy savings
over time make it less expensive in the long run. Final
