The general rule is his salary will be 32000*(1.04)^n, where n is the number of years.
\n" ); document.write( "40,000=32,000(1.04)^n
\n" ); document.write( "divide both sides by 32,000
\n" ); document.write( "(5/4)=1.04^n
\n" ); document.write( "take ln both sides
\n" ); document.write( "ln(5/4)=nln(1.04)
\n" ); document.write( "divide ln (5/4)/ln(1.04)=5.69 years, so it will take 6 years to exceed $40,000. $32,000*(1.04)^6=$40,490 \n" ); document.write( "

\n" );
