解题思路:

注意事项:

参考代码:

import java.util.Scanner;

public class Main {

public static void main(String[] args){

Scanner scanner=new Scanner(System.in);

int k,n;

double p,l;

do {

k=scanner.nextInt();}while(100>k||k>10000);

do {

n=scanner.nextInt();}while(1>n||n>48);

do {

p=scanner.nextDouble();}while(0.001>p||p>0.01);

double sum=k;

double r=0;

for(int i=1;i<=n;i++) {

l=sum*p;

r+=l;

sum+=l+k;

}

System.out.printf("%.2f",r-0.005);

}

}
