Answer
$\$ 22,000$
Work Step by Step
The future value ($FV=30,360$) of an investment of
$PV=?$ dollars
at an annual simple interest rate of
$r =9.5\displaystyle \%=\frac{9.5}{100}=0.095$
for a period of
$t = 4$ years
is
$FV=PV(1+rt)$
To find PV, divide both sides with $(1+rt)$:
$ PV=\displaystyle \frac{FV}{(1+rt)}=\frac{30,360}{1+0.095\cdot 4}\approx$22,000
