You can put this solution on YOUR website!
Let x= hours that the car has been parked so:\r
\n" ); document.write( "\n" ); document.write( "for example you have to pay 4+2,5(2) for 3 hours then in gral\r
\n" ); document.write( "\n" ); document.write( "you have to pay 4 +2,5(x-1)for x hours \r
\n" ); document.write( "\n" ); document.write( "so you have to resolve 4 +2,5(x-1)> 16,5 so 2,5(x-1)>12,5 so 2,5x>15 so x>6\r
\n" ); document.write( "\n" ); document.write( "R:The car has been parked for more than 6 hours
\n" ); document.write( "
\n" );
