Answer:

The answer is 2250 packets.

Explanation:

The round trip delay is about 540 millisec, so with a 50 Mbps channel the bandwidth product delay is 27 megabits or 3.375.000 bytes. With packets of 1500 bytes, it takes 2250 packets to fill hte pipe, so the window should be at least 2250 packets.

       System.out.println("Total expenses is "+totalExpenses);

System.out.println("The amount over your budget is "+ Math.abs(monthBudget-totalExpenses));

   }

}

Explanation:

  • Using Java programming language
  • Prompt user for month's budget
  • Use Scanner class to receive and store the amount entered in a variable
  • Use a do while loop to continuously request user to enter amount of expenses
  • Use a variable totalExpenses to add up all the expenses inside the do while loop
  • Terminate the loop when user enters 0 as amount.
  • Subtract totalExpenses from monthBudget and display the difference as the amount over the budget
