Salary = x
\n" ); document.write( "commission = y\r
\n" ); document.write( "\n" ); document.write( "x+3800*0.01y=594
\n" ); document.write( "x+5750*0.01y=652.50\r
\n" ); document.write( "\n" ); document.write( "x+38y=594
\n" ); document.write( "x+57.5y=652.50\r
\n" ); document.write( "\n" ); document.write( "subtract the two
\n" ); document.write( "19.5y = 58.50
\n" ); document.write( "y= 58.50/19.5
\n" ); document.write( "y=3% the commission\r
\n" ); document.write( "\n" ); document.write( "plug value of y in first equation\r
\n" ); document.write( "\n" ); document.write( "x+3800*0.03=594
\n" ); document.write( "x+114=594
\n" ); document.write( "x=594-114
\n" ); document.write( "x=$480 the salary per week\r
\n" ); document.write( "\n" ); document.write( "..
\n" ); document.write( "480+0.03*4325=$609.75
\n" ); document.write( "
\n" );
