  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 dis , amount ; 
  
    printf("\nEnter the Distance : ") ;
    scanf( "%f" , &dis ) ;
  
    if ( dis <= 30 )
    {
      amount = dis * 50 ;
    }
    else
    {
      amount = 30 * 50 + ( dis - 30 ) * 40 ;
    }
  
    printf( "\nThe Amount is %.2f " , amount ) ;
    
    return 0;
  }
