n = number of chairs purchased
\n" ); document.write( "p = price paid per chair
\n" );
document.write( "np = 10,000 so p=10,000/n
\n" );
document.write( "(n-1)(p+50)=10450
\n" );
document.write( "np+50n-p-50=10450
\n" );
document.write( "10000+50n-(10000/n)-50=10450
\n" );
document.write( "Subtract 10,000 from both sides and add 50 to both sides. Add 50n and 10,000/n by using n as the common denominator.
\n" );
document.write( "(50n^2 - 10000)/n = 500
\n" );
document.write( "50n^2 - 10000 = 500n
\n" );
document.write( "50n^2 - 500n - 10000 =0
\n" );
document.write( "n^2 - 10n - 200 = 0
\n" );
document.write( "(n-20)(n+10)=0
\n" );
document.write( "n=20 and n=-10
\n" );
document.write( "Can't use -10 because there can't be a negative number of chairs. The answer is 20.\r
