Answer
$\$ 787.40$
Work Step by Step
The future value ($FV=1000$) of an investment of
$PV=?$ dollars
at an annual simple interest rate of
$r =4.5\displaystyle \%=\frac{4.5}{100}=0.045$
for a period of
$t = 6$ years
is
$FV=PV(1+rt)$
To find PV, divide both sides with $(1+rt)$:
$ PV=\displaystyle \frac{FV}{(1+rt)}=\frac{1000}{1+0.045\cdot 6}\approx$787.401574803
