/*Exercise 2 - Selection

Write a program to calculate the amount to be paid for a rented vehicle.

•	Input the distance the van has travelled
•	The first 30 km is at a rate of 50/= per km.
•	The remaining distance is calculated at the rate of 40/= per km.


e.g.

Distance -> 20
Amount = 20 x 50 = 1000


Distance -> 50
Amount = 30 x 50 + (50-30) x 40 = 2300*/

#include <stdio.h>
int main ( void ){
	int distance;
	float rate;
	
	printf( "Enter the distance : " );
	scanf ( "%d", &distance );
	
	if ( distance <= 30 ){
		rate = distance * 50.0;
	}
	
	else
	    rate = 30 * 50.0 + ( distance - 30 ) * 40.0;
	    
    printf( "the rate is %.2f\n", rate );
    
    return 0;
    
}
