/*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() {
  
  float distance,extra;

  printf("Enter distance : ");
  scanf("%f",&distance);

  if( distance > 30)
  {
    extra = distance - 30;

    printf("amount to be paid : %.2f",( 30 * 50) + ( extra * 40));
  }

  else
  {
    printf("amount to be paid : %.2f",distance * 50);
  }
  return 0;
}
