Dear my friend,

I live in Ohio and go to a High School. I am currently doing a science fair project on solar energy. I am comparing a stationary solar cell system to a one axis tracking system. I am wondering if anyone would be able to give me a price quote of a fixed solar system and a movable one. Your help would be much appreciated.

I have already sent e-mail to three different “solar” companies. As of now, none have returned. If you answer, and want the more details of my project feel free to contact me.

Sincerely,
Zubacat

My absent minded uncle owns a agame and hobby store. His store caries eight different chess sets. The least expensice set sells for $5 and the most expensice one sells for $196. He has arranged them on the shelf in increasing order from the least expensive to the most expensive. He has a problem... he cant remember the prices of the other 6 chess sets. He does remember that the price of the third chess set equals the price of the first and second sets combined. The prices for the fifth, sixth, seventh, and eight sets also follow this rule. What is the cost of each of the eight chess sets?

Please show ur work, so i can understand!!
thnx
