Write a program with a car's miles/gallon and gas dollars/gallon (both doubles) as input, and output the gas cost for 20 miles, 75 miles, and 500 miles. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: System.out.printf("%.2f", yourValue); The output ends with a new line. Ex: If the input is: 20.0 3.1599 the output is: 3.16 11.85 79.00

Question

Driving is expensive. Write a program with a car's miles/gallon and gas dollars/gallon (both doubles) as input, and output the gas cost for 20 miles, 75 miles, and 500 miles.

Output each floating-point value with two digits after the decimal point, which can be achieved as follows:
System.out.printf("%.2f", yourValue);

The output ends with a new line.

Ex: If the input is:

20.0 3.1599

the output is:

3.16 11.85 79.00

For some reason my code is not functioning for all inputs to display the requested outputs. 

this is my code used: 

import java.util.Scanner;

public class LabProgram {
public static void main(String[] args) {


Scanner sc = new Scanner(System.in);

double n1 = sc.nextDouble();
double n2 = sc.nextDouble();

double product1 = n2*20/20;
double product2 = n2*75/20;
double product3 = n2*500/20;

System.out.printf("%.2f %.2f %.2f",product1,product2,product3);
System.out.println();
}
}

this one is showing correctly:

Input
20.0 3.1599
Your output
3.16 11.85 79.00
Expected output
3.16 11.85 79.00
 
but this one is showing incorrectly:
 
Input
30.0 3.8999
Your output
3.90 14.62 97.50
Expected output
2.60 9.75 65.00
