First year:10000+(0.10)(100000)=110000
\n" ); document.write( "Second year:110000+(0.10)(110000)=121000
\n" ); document.write( "Third year: 121000-(.10)(121000)=121000-12100=108900
\n" ); document.write( "Fourth year: 108900-(0.10)(108900)=108900-10890=98010
\n" ); document.write( "ANSWER: After 4 years the population was 98010.
