\n" ); document.write( "Hi,
\n" ); document.write( "20,000 bacteria are present in a culture 2 hours after beginning with 15,000 bacteria. that is 5,000 new bacteria in 2 hours
\n" ); document.write( "Setting up the proportion, letting x represent the amount of growth in 15hr
\n" ); document.write( "\"5000%2F2hr+=+x%2F15hr\"
\n" ); document.write( "cross multiply to solve
\n" ); document.write( "2x = 15*5000
\n" ); document.write( "x = 37,500 growth in 15hr
\n" ); document.write( "Total bacteria: 15,000 + 37,500 = 52,500 \n" ); document.write( "
\n" );
