Let multiplicative factor-cost be x\r\n" );
document.write( "Then amount spent on pens, pencils, and markers = 4x, 5x, and x, respectively\r\n" );
document.write( "Total amount spent on all 3 items = 4x + 5x + x = 10x\r\n" );
document.write( "\r\n" );
document.write( "Amount spent on pens, and on markers = 4x, and x, respectively, so total = 4x + x = 5x\r\n" );
document.write( "Also, itw’s given that $50 was spent on pens and markers, and so, we get:  5x = 50\r\n" );
document.write( "Multiplicative factor, or \r\n" );
document.write( "\r\n" );
document.write( "With multiplicative factor, x, being 10, amount spent on pens = 4(10) = $40\r\n" );
document.write( "This means that amount spent on markers = $50 - $40 = $10\r\n" );
document.write( "In addition, amount spent on pencils = 10x - 50, or 10(10) - 50 = 100 - 50 = $50\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Amount spent on pens = $40, and with 3 pens costing $1, \r\n" );
document.write( "\r\n" );
document.write( "  \r\n" );
document.write( "                                                         Number of pencils bought: \r\n" );

document.write( "\r\n" );
document.write( "\r\n" );
document.write( "As seen, 20 pencils were purchased for $50, so each pencil cost: \r\n" );
document.write( "Therefore, $175 could buy
