document.write( "An art dealer sold two artworks for $1520 thereby making a profit of 25% on the first and 10% profit on the other, whereas if he had approached any exhibition he would have sold them together for $1535 with a profit of 10% on the first and 25% on the other artwork. Find the actual cost of each artwork. \n" );

Algebra.Com's Answer #57959 by dolly(163)![]() ![]() ![]() You can put this solution on YOUR website! Let the cost of the first art work = $x \n" ); document.write( "Profit = 25% = 0.25 \n" ); document.write( "So sale price = x + 0.25x \n" ); document.write( " = 1.25x \n" ); document.write( "Let the cost of the second art work = $y \n" ); document.write( "Profit = 10% = 0.10 \n" ); document.write( "So sale price = y + 0.10y \n" ); document.write( " = 1.10y\r \n" ); document.write( "\n" ); document.write( "Total sale price given = $1520\r \n" ); document.write( "\n" ); document.write( "==> 1.25x + 1.10y = 1520 ------------(1)\r \n" ); document.write( "\n" ); document.write( "Case (ii)\r \n" ); document.write( "\n" ); document.write( "Profit on first work = 0.10 \n" ); document.write( "so sale price = 1.10x\r \n" ); document.write( "\n" ); document.write( "Profit on second work = 0.25 \n" ); document.write( "so sale price = 1.25y \r \n" ); document.write( "\n" ); document.write( "Total sale price given = $1535\r \n" ); document.write( "\n" ); document.write( "==> 1.10x + 1.25y = 1535 ------------(2)\r \n" ); document.write( "\n" ); document.write( "Adding 1 and 2 we get, 2.35x + 2.35y = 3050\r \n" ); document.write( "\n" ); document.write( "==> x + y = 1300 [dividing by 2.35 throughout]------(3)\r \n" ); document.write( "\n" ); document.write( "Subtracting 1 and 2 we get, 0.15x - 0.15y = - 15\r \n" ); document.write( "\n" ); document.write( "==> x - y = -100 [dividing by 0.15 throughout]------(4)\r \n" ); document.write( "\n" ); document.write( "Adding 3 and 4, 2x = 1200 \n" ); document.write( "==> x = 600\r \n" ); document.write( "\n" ); document.write( "plugging in (3), we get y = 700\r \n" ); document.write( "\n" ); document.write( "Thus the art works cost $600 and $ 700 respectively.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
