Let x = the number of nickels, x+3 = the number of dimes, and 2(x+3) = the number of quarters.\r \n" ); document.write( "\n" ); document.write( "So, your equation is \n" ); document.write( "5x+10(x+3)+25(2(x+3))=375 \n" ); document.write( "5x+10x+30+50x+150=375 \n" ); document.write( "65x+180=375 \n" ); document.write( "65x+180-180=375-180 \n" ); document.write( "65x=195 \n" ); document.write( "x=3 \n" ); document.write( "So number of nickels = 3 or .15 \n" ); document.write( "Dimes = 6 or .60 \n" ); document.write( "Quarters = 12 or 3.00\r \n" ); document.write( "\n" ); document.write( "Value of coins = $3.75 \r \n" ); document.write( "\n" ); document.write( "Good luck! \n" ); document.write( " |
