Algebra.Com's Answer #656165 by Boreal(15235)![]() ![]() You can put this solution on YOUR website! the points are (2,640) and (5,700) \n" ); document.write( "The slope is (700-640)/(5-2) \n" ); document.write( "That is 60/3 or 20. \n" ); document.write( "Slope is 20. \n" ); document.write( "Use point slope formula with either point \n" ); document.write( "y-640=20(x-2) \n" ); document.write( "y-640=20x-40 \n" ); document.write( "y=20x+600 \n" ); document.write( "use other point to check \n" ); document.write( "y-700=20(x-5) \n" ); document.write( "y=20x+600. The marginal cost per handbag is 20 dollars. It is assumed here that with 0 bags, the cost of having the materials and space is 600, and every handbag will cost an additional $20 with the fixed cost of $600 remaining. \n" ); document.write( " |
