	public static void main(String[] args) throws IOException {
		
		BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
		StringTokenizer st = new StringTokenizer(br.readLine()," ");
		int up = Integer.parseInt(st.nextToken());
		int down = Integer.parseInt(st.nextToken());
		int height = Integer.parseInt(st.nextToken());

		if ((height-down)%(up-down)==0) {
			System.out.print((height-down)/(up-down));
		}
