A demand equation (sometimes called a demand curve) shows how much money people would pay for a product depending on how much of that product is available on the open market. Often, the demand equation is found empirically (through experiment, or market research). a) Suppose 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 month’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 ). Using the two points (42, 20) and (52, 10) in the slope equation m= y 2 –y 1 /x 2 – x 1 = 10-20/ 52-42= -10/10= -1. Using m=-1 and the point
