Need help what to code to get the 10% of the amount

Question

You take a loan from a friend and need to calculate how much you will owe him after 3 months.
You are going to pay him back 10% of the remaining loan amount each month.
Create a program that takes the loan amount as input, calculates and outputs the remaining amount after 3 months.

I would suggest you create a variable, make it a double as it will need to handle decimals.

Then you apply the math for calculating a tip, amount * 0.1 which will give you an answer, but also include a lot of unwanted decimals.

So we want to round out the answer.

A quick google search returns Math.round() with an explanation on how to get the desired number of decimal places.

I hope this snippet helps explain further

//your code goes here
double tip = Math.round(amount * 0.1 *10);
tip /= 10;
System.out.println(tip);
}
}

Rik Wittkopp you mean these?

import java.util.Scanner;

public class Program
{
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int amount = scanner.nextInt();
//your code goes here

}
}

Answer 4

//your code goes here Good Luck

int x=1;
while(x<=3) {
amount -= amount * 0.1;
x++;
}
System.out.println(amount);
