1. Calculate the discount factor now for the cash flow in 17th years, assuming a 5% annual interest rate, compounded annually. Round up to two decimal places(e.g., 20.344=20.34 ; 20.345-20.35) (Required) 2. Calculate the discount factor for the cash flow in 12th years, assuming an annual interest rate of 20%, compounded 12 times per year. Round up to two decimal places(e.g., 20.344=20.34; 20.345=20.35) (Required) 3. Given a series of cash flows (400, 500, 600, 700) (in the order of now, one year, two years, and three years), calculate what the present value is at 8% compounded annual interest (one interest payment per year). Round up to two decimal places(e.g., 20.344=20.34; 20.345=20.35) (Required)
