Compact fluorescent bulbs cost 10 per bulb and last 10 years. Tungsten bulbs cost 0.50 per bulb and last 1 year.
 
  For a given amount of light, a tungsten bulb draws 75 W
  and a compact fluorescent bulb draws 10 W. If the cost of electricity is 0.10/kWh and the
  bulbs are operated for 2000 h/yr, what amount of money is saved by use of a compact
  fluorescent instead of a tungsten bulb over a 20-year period?
