Answer 1

// here is code in java.

import java.util.*;

// class defintion

class Main

{

// main method of the class

public static void main (String[] args) throws java.lang.Exception

{

try{

// scanner object to read input string

Scanner s=new Scanner(System.in);

// variables

double amount;

int ch;

double bef_tax, aft_tax;

System.out.print("Please enter the jackpot amount:");

// read the amount from user

amount=s.nextDouble();

System.out.print("enter Payment choice (1 for cash, 2 for installments): ");

// read the choice

ch=s.nextInt();

// if choice is cash then calculate amount before and after the tax

if(ch==1)

{

bef_tax=amount*.65;

aft_tax=(amount*.70)*.65;

System.out.println("instantly received amount before tax : "+bef_tax);

System.out.println("instantly received amount after tax : "+aft_tax);

}

// if choice is installment then calculate amount before and after the tax

else if(ch==2)

{

bef_tax=amount/20;

aft_tax=(amount*.70)/20;

System.out.println("installment amount before tax : "+bef_tax);

System.out.println("installment amount after tax : "+aft_tax);

}

}catch(Exception ex){

return;}

}

}

Step-by-step explanation:

Read the jackpot amount from user.Next read the choice of Payment from user. If user's choice is cash then calculate 65% instantly amount received by user before and after the 30% tax.Print both the amount.Similarly if user's choice is installments then find 20 installments before and after 30% tax.Print the amount before and after the tax.

Output:

Please enter the jackpot amount:200

enter Payment choice (1 for cash, 2 for installments): 2

installment amount before tax : 10.0

installment amount after tax : 7.0
