Compact fluorescent bulbs typically last 10 years while incandescent bulbs last about 1 year.
 
  For a given amount of light, a tungsten bulb draws 100 W and a compact
  fluorescent bulb draws 15 W. If the cost of electricity is 0.10/kWh, how long would you
  have to operate a compact fluorescent bulb to save 5.00 compared to the costs of operating
  a tungsten bulb?
