Determine the combined present value as of December 31, 2016, of the following four payments to be received at the end of each of the designated years, assuming an annual interest rate of 8%. (FV of $1, PV of $1, FVA of $1, PVA of $1, FVAD of $1 and PVAD of $1). Find N as well.

Payment			Year Received
$	5,000		2017
	6,000		2018
	8,000		2020
	9,000		2022

2017 I=8% N=? PAYMENT= $5,000 PV=?

2018 I=8% N=? PAYMENT= $6,000 PV=?

2019 I=8% N=? PAYMENT= $8,000 PV=?

2020 I=8% N=? PAYEMNT= $9,000 PV=?
