Suppose that a market research company finds that at a price of p = $27, they would sell x = 27 tiles each month.
\n" ); document.write( " If they lower the price to p = $17, then more people would purchase the tile, and they can expect to sell x = 37 tiles in a month’s time.
\n" ); document.write( "Find the equation of the line for the demand equation.
\n" ); document.write( "Write your answer in the form p = mx + b.
\n" ); document.write( ":
\n" ); document.write( "We will use the slope formula and the point/slope formula, but
\n" ); document.write( "instead of x & y, we will use x & p
\n" ); document.write( "Assign the given values as follows
\n" ); document.write( "x1 = 27; p1 = 27
\n" ); document.write( "x2 = 37; p2 = 17
\n" ); document.write( "Find the slope
\n" ); document.write( "m = \"%2827+-+17%29%2F%2837+-+27%29\" = \"%28-10%29%2F%2810%29\" = -1 is the slope
\n" ); document.write( "Find the equation
\n" ); document.write( "p - 27 = -1(x - 27)
\n" ); document.write( "p - 27 = -x + 27
\n" ); document.write( "p = -x + 54 is the demand equation
\n" ); document.write( ":
