Let $\"+x+\"$ = the number of questions on the test
\n" ); document.write( "given:
\n" ); document.write( " $\"+5+\"$ = number missed
\n" ); document.write( " $\"+x+-+5+\"$ = number that are right
\n" ); document.write( " $\"+%28+x+-+5+%29+%2F+x+=+.89+\"$
\n" ); document.write( " $\"+x+-+5+=+.89x+\"$
\n" ); document.write( " $\"+.11x+=+5+\"$
\n" ); document.write( " $\"+x+=+5%2F.11+\"$
\n" ); document.write( " $\"+x+=+45.45+\"$
\n" ); document.write( "There are 45 questions on the test
\n" ); document.write( "check:
\n" ); document.write( " $\"+%28+45+-+5+%29+%2F+45+=+40%2F45+\"$
\n" ); document.write( " $\"+40%2F45+=+.8888+\"$
\n" ); document.write( "This is about 89% \n" ); document.write( "
