C(x)=x^2-10x+61
\n" ); document.write( "8500=x^2-10x+61
\n" ); document.write( "x^2-10x-8439=0
\n" ); document.write( "x=(1/2)(10+/-sqrt (100+33756)); sqrt term=184
\n" ); document.write( "x=(1/2)(10+184), positive root only
\n" ); document.write( "x=97 units ANSWER
\n" ); document.write( "check
\n" ); document.write( "97^2-970+61=9409-970+61=$8500
