If a cell phone depreciates 20% every year, then its value is 80% of the year before. So, after t years we have:
\n" ); document.write( "V(value)=250 x (.8)^t
\n" ); document.write( "After 6 years, we have:
\n" ); document.write( "V=250 x (.8)^6=250 x 0.262144=$65.536 as the value of the phone. ☺☺☺☺ \n" ); document.write( "

\n" );
