Let $\"x\"$ = number of solid-color ones sold
\n" ); document.write( "Then $\"40+-+x\"$ = number of print ones sold
\n" ); document.write( "given:
\n" ); document.write( "Sales of solid-color DISABLED_event_ones= $\"9.9x\"$
\n" ); document.write( "Sales of print ones sold = $\"12.75%2A%2840+-+x%29\"$
\n" ); document.write( " $\"9.9x+%2B+12.75%2A%2840+-+x%29+=+421.65\"$
\n" ); document.write( "-----------------------------
\n" ); document.write( " $\"9.9x+%2B+510+-+12.75x+=+421.65\"$
\n" ); document.write( " $\"-2.85x+=+-88.35\"$
\n" ); document.write( " $\"x+=+31\"$
\n" ); document.write( " $\"40+-+x+=+40+-+31\"$
\n" ); document.write( " $\"40+-+31+=+9\"$
\n" ); document.write( "31 solid-color ones and 9 print ones were sold
\n" ); document.write( "check:
\n" ); document.write( " $\"9.9x+%2B+12.75%2A%2840+-+x%29+=+421.65\"$
\n" ); document.write( " $\"9.9%2A31+%2B+12.75%2A%2840+-+31%29+=+421.65\"$
\n" ); document.write( " $\"306.9+%2B+114.75+=+421.65\"$
\n" ); document.write( " $\"421.65+=+421.65\"$
\n" ); document.write( "OK \n" ); document.write( "
