let x = the # of dimes
\n" ); document.write( " 6x = the # of quarters\r
\n" ); document.write( "\n" ); document.write( ".1x+ .25(6x) = 28.8
\n" ); document.write( ".1x + 1.5x = 28.8
\n" ); document.write( "1.6x=28.8
\n" ); document.write( "x = 28.8 / 1.6
\n" ); document.write( "x = 18
\n" ); document.write( "6x = 6 x 18 = 108\r
\n" ); document.write( "\n" ); document.write( "18 dimes and 108 quarters
\n" ); document.write( "
