document.write( "Question 411557: A market research company finds that a the 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 tiles, 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 the form p=mx +b. Hint: write an equation using points in the form (x,p). \n" ); document.write( "
