I'm venting!!! Most people don't know that Hurricane Katrina's eye hit the gulf coast of Mississippi (Waveland, Bay St. Louis, Pass Christian). The whole coast was wiped out! Have someone drop you off on a deserted sand beach with nothing in site and only your car keys; that's the MS gulf coast. This was a storm that literally sucked the water out of the bay and gulf sound, then threw it back in on 5, 40 foot waves; along with all of the debris.

New Orleans was not the prime site for the Hurricane. The Corp. of Engineers did not build the levees high enough and the City of N.O. didn't use the money appointed to keep the tax payers safe. Had they done their civic duty and the levees held, there would have been no damage.

The good people of the Mississippi Gulf Coast haven't done all of the crying and moaning as the City of N.O. and I suppose the "squeaky wheel gets the grease". There is another saying, "the squeaky wheel gets replaced".... God love us all. AMEN

an energy-efficient lightbulb,taking in 28.0 W of power,can produce the same level of brightness as a conventional bulb operating at a power 100W.the life time of the energy efficient bulb is 10000 h and its purchase price is $17.0,whereas the conventional bulb has life time 750h and costs $0.420 per bulb.

Determine the total savings obtained by using one energy-efficient bulb over its life time,as opposed to using conventional bulbs over the same time of period?
assume an energy cost of $0.0800 per Kilowatt-hour.

We are debating whether or not to stay on Earth or go to another planet. My group has the stay on Earth side. Any good rebuts, reasons, or arguments to the other side.
