(Again, assume you can earn 6 percent on this deposit)

Explanation / Answer

a)
n=15
rate =0.06
FV=70,000
=PMT(0.06,15,0,-70000)
Using excel pmt function:
=PMT(0.06,15,0,-70000)
=$3,007.39

b)For a lumpsum:
n=15
pmt=0
FV=70000
=PV(0.06,15,0,70000)
=$29,208.55

c) Value of 20,000 at present is 20000/(1.06^5)=$14,945.16
Hence PV=-14945.16
FV=70,000
rate =0.06
n=15
Using excel pmt function:
.=PMT(0.06,15,-14945.1635,70000)
=$1,468.60
