bought a car for $10,000
\n" ); document.write( "four years lost 20% ($2000) | Depreciated $500 per year
\n" ); document.write( "Let x represent the number of years...
\n" ); document.write( "Depreciate Value = 10000 - 500x\r
\n" ); document.write( "\n" ); document.write( "when the car is only worth $1,000?
\n" ); document.write( "1000 = 10000 - 500x
\n" ); document.write( "500x = 10000-1000
\n" ); document.write( "500x = 9000
\n" ); document.write( "x = 9000/500
\n" ); document.write( "x = 18 years, when the car is only worth $1,000
\n" ); document.write( "
\n" );
