You can put this solution on YOUR website!

use Present Value table to find:
Present Value Factor: n%2Fr, where Number of periods = n and Interest rate = r

a.
n%2Fr=0.3855
PV+=+%280.386+%2A+800%29+=+308.80
b.
n%2Fr=0.7835
PV+=+%280.7835%2A+300%29+=235.05
c.
n%2Fr=0.7894
PV+=+%280.7894%2A+1000%29+=789.4
d.
n%2Fr=0.23256
PV+=+%280.23256%2A+1000%29+=232.56
