let x = original cost of the books.
\n" ); document.write( "x - .35x = 633.75
\n" ); document.write( "factor to get:
\n" ); document.write( "x * (1-.35) = 633.75
\n" ); document.write( "simplify to get:
\n" ); document.write( ".65 * x = 633.75
\n" ); document.write( "divide both sides by .65 to get:
\n" ); document.write( "x = 633.75 / x
\n" ); document.write( "simplify to get:
\n" ); document.write( "x = $975.00
\n" ); document.write( "
\n" ); document.write( "
\n" );
