If a 16-page document is split between this printer and an older model, the two printers take 50 s to print the document, working together.

Algebra.Com's Answer #132106 by MathTherapy(10552)![]() ![]() You can put this solution on YOUR website! Since the laser printer can print 1 page in 15s, it follows that it can print 16 pages in 240s. With this 16-page job taking both printers 50s, it means, obviously that the older printer is faster than the laser printer.\r \n" ); document.write( "\n" ); document.write( "Since the laser can print 16 pages in 240s, then it can print \n" ); document.write( "\n" ); document.write( "To find what fraction of the 16-page job the old printer can do in 1 sec., when doing the job with the laser, we have: \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "5 + 1200a = 24 \n" ); document.write( "1200a = 19 \n" ); document.write( "a = \n" ); document.write( "\n" ); document.write( "Since in 1 sec., the older printer does \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "19a = 1,200\r \n" ); document.write( "\n" ); document.write( "a = \n" ); document.write( "\n" ); document.write( "This means that by itself, the older printer can do the entire 16-page job in 63.15789 seconds, which means that it can do 1 page in \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
