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, them 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 the answer in p = mx + b form.
