4800*.25=1200 IS THE ANNUAL DEPRECIATION.
\n" ); document.write( "FIRST YEAR AFTER PURCHASE - 4800-1200=3600
\n" ); document.write( "SECOND YEAR 3600-1200=2400
\n" ); document.write( "THIRD YEAR 2400-1200=1200
\n" ); document.write( "FOURTH YEAR 1200-1200=0 NO VALUE LEFT.
\n" ); document.write( "OR IF IT IS 25% OF THE REMAING VALUE THEN WE HAVE:
\n" ); document.write( "4800*.75=3600 @ THE END OF YEAR 1
\n" ); document.write( "3600*.75=2700 @ THE END OF YEAR 2
\n" ); document.write( "2700*.75=2025 @ THE END OF YEAR 3
\n" ); document.write( "2025*.75=1518.75 @ THE END OF YEAR 4
\n" ); document.write( "1518.75*.75=1139.O6 @ THE END OF YEAR 5.
\n" ); document.write( "1139.06*.75=854.30 @ THE END OF YEAR 6 ETC. \r
