\n" ); document.write( "Let \"x\"=unknown, mixed with face cream that cost 3360.00.
\n" ); document.write( "\"y=12L\"=face cream that cost 1120.00
\n" ); document.write( "\"highlight%28z=x%2By=x%2B12%29\"=resultant mixture of \"x\" & \"y\" when mixed that cost 1650.00
\n" ); document.write( "It follows the eqn when mixed:
\n" ); document.write( "
\n" ); document.write( "Subst. highlighted:
\n" ); document.write( "\"%283360%2FL%29%28x%29%2B13440=%281650%2FL%29%28x%2B12L%29\"
\n" ); document.write( "\"%283360%2FL%29%28x%29%2B13440=%281650%2FL%29%28x%29%2B19800\"
\n" ); document.write( "\"%283360%2FL%29x-%281650%29x=19800-13440\"
\n" ); document.write( "\"%281710%2FL%29%28x%29=6360\"
\n" ); document.write( "

\n" ); document.write( "Check by going back:
\n" ); document.write( "\"3360%283.72%29%2B13440=1650%283.72%2B12%29\"
\n" ); document.write( "\"12499.20%2B13440=1650%2815.72%29\"
\n" ); document.write( "\"25939.20%3E=25938.00\" close enough bec we round off.
