p = 4c
\n" ); document.write( "2p = 6c+6000 substitute for p:
\n" ); document.write( "2(4c) = 6c+6,000
\n" ); document.write( "8c = 6c+6,000
\n" ); document.write( "2c = 6,000
\n" ); document.write( "c = 3,000
\n" ); document.write( "so the cars cost 3,000 each.
\n" ); document.write( "And the planes, the problem says p = 4c, thus p = 4(3,000), p = 12,000 each plane costs 12,000
\n" ); document.write( "
\n" );
