we are talking about a span of 15 years
\n" ); document.write( ":
\n" ); document.write( "so we need to figure out how much the salary increased on a yearly basis
\n" ); document.write( ":
\n" ); document.write( "15000-5100=9900 the amount of increase over 15 years
\n" ); document.write( ":
\n" ); document.write( "9900/15=660
\n" ); document.write( ":
\n" ); document.write( "so salaries have increased by 660 dollars per year
\n" ); document.write( ":
\n" ); document.write( "S(t)=660t+5100.......is our equation :t is time in years
\n" ); document.write( ":
\n" ); document.write( "2010 would be year 24
\n" ); document.write( ":
\n" ); document.write( "S(24)=660(24)+5100=15840+5100=$20940
\n" ); document.write( ":
\n" ); document.write( "so this equation predicts that the Avg Salary in 2010 will be $20,940 \n" ); document.write( "

\n" );
