 Question 261713: A market research company finds that at a price of p=\$20., they would sell x=42 tiles each month. If they lower the price to p=\$10., then more people would purchase the tile, and they can expect to sell x=52 tiles in a months's time. Find the equation of the line for the demand equation. Write your answer in the form p=mx+b. Hint: write an equation using two points in the form (x,p). My biggest problem is I am not sure about the demand equation, I am not real clear on what I am suppose to be figuring out in this problem. I have several other problems which depend on my having this base correct. I am totally blank and have read everything I have on this and I must be over looking or thinking this out. Please help me.

 Question 262846: I do not know where to start. A red ball and a green ball are simultaneously tossed into the air. Find a polynomial D(t) that represents the difference in the heights of the two balls. The red ball is given an initial velocity of 96 feet per second, and its height t seconds after it is tossed is -16t^2 + 96t feet. The green ball is given an initial velocity of 80feet per second, and its height t second, and its height t seconds after it is tossed is -16t^ + 80t feet. How much higher is the red ball 2 seconds after the balls are tossed? In reality, when does the difference in the heights stop increasing? Click here to see answer by ankor@dixie-net.com(15624)
