\n" ); document.write( "given:
\n" ); document.write( " $\"+40x+%2B+40%2A%28+x+%2B+25+%29+=+2600+\"$
\n" ); document.write( " $\"+40%2A%28+x+%2B+x+%2B+25+%29+=+2600+\"$
\n" ); document.write( " $\"+2x+%2B+25+=+65+\"$
\n" ); document.write( " $\"+2x+=+40+\"$
\n" ); document.write( " $\"+x+=+20+\"$
\n" ); document.write( " $\"+x+%2B+25+=+45+\"$
\n" ); document.write( "The hourly rate of the apprentice is $20/hr
