The value of a car is inversely
\n" ); document.write( "proportional to its age
\n" ); document.write( "V = k/A
\n" ); document.write( "First find value of k
\n" ); document.write( "4900 = k/4
\n" ); document.write( "k = 4900 x 4
\n" ); document.write( "k = 19600
\n" ); document.write( "Formula:
\n" ); document.write( "V = 19600/A
\n" ); document.write( "2800 = 19600/A
\n" ); document.write( "A = 19600/2800
\n" ); document.write( "A = 7 years
\n" ); document.write( "Hope this helps:-)
