300=175+.5x
\n" ); document.write( "The correct formula is:
\n" ); document.write( "300=175+.05x
\n" ); document.write( ".05x=300-175
\n" ); document.write( ".05x=125
\n" ); document.write( "x=125/.05
\n" ); document.write( "x=$2,500 is the amount of her sales.
\n" ); document.write( "Proof:
\n" ); document.write( "300=175+.05*2,500
\n" ); document.write( "300=175+125
\n" ); document.write( "300=300
\n" ); document.write( "
\n" );
