The initial value of the computer is given as $4,000.00
\n" ); document.write( "In 3 year's time, its value is reduced to $400.00, so it has lost $3,600.00 ($4,000.00-$400.00), so the annual loss (L) as a linear function is:
\n" ); document.write( " $\"L+=+3600%2F3\"$
\n" ); document.write( " $\"L+=+1200\"$ dollars per year.
\n" ); document.write( "If a is the number of years, then the linear function that relates the value of the computer (V) to the age of the computer (a) in years is just:
\n" ); document.write( " $\"highlight%28V%28a%29+=+4000-1200a%29\"$ \n" ); document.write( "

\n" );
