Cake Eater, Java
===

    public class CakeEater{
    	public static void main(String[]args){
    		int a=Integer.parseInt(args[1]),b=Integer.parseInt(args[2]),c=Integer.parseInt(args[3]);
    		System.out.println((int)Math.min(a,((1.2+Math.random()*0.15)*a)/c));
    	}
    }

It eats cake. That's about it.
