Please find what's wrong in this program. When we enter run: input — 2, output — 55, expected— 55. But my 5 tests are failed

Question

import java.util.*;
public class Paint_cost
{
public static void main(String[] args) {
Scanner in = new Scanner (System.in);
int i;
System.out.println("enter the number of paints bought");
i= in.nextInt();
int paint= i*5;
int total= paint + 40;
int tax= (10*total)/100;
int cost= total + tax;
System.out.println("paint cost ="+cost);
}
}

Answer 1

your solution prints unnecessary additional text. look at my solution and compare ... excuse me for my english

import java.util.Scanner;

public class Program
{
public static void main(String[] args) {
Scanner in = new Scanner (System.in);
double ncolors,project = 40.00;
ncolors = in.nextDouble();
project+=(ncolors * 5);

project = project + project * 0.1;
System.out.printf("%.0f",project );

}
}
