Question

7. If you invest the amount of P at R% interest rate annually. In N years, your investment will be P[1-(R/100)N+1] / (1 – R/100). Accepts the input of P, R and N and compute the amount of money earned after N years using computer currency format.
(Note: Math.pow(A,B) - A raise to the power of B)

Answer 1

import java.util.Scanner;

public class main
{
