Answer
$\$27,158.61$
Work Step by Step
The inflation can be calculated as:
$FV=PV\times (1+r)^{t}$
Here, the future value of the car is $\$30,000$
The inflation rate is $r=1\%$
The number of 6-months periods is $t=5\times 2=10$
Therefore the present value is:
$FV=PV\times (1+r)^{t}$
$PV=\frac{FV}{ (1+r)^{t}}=\frac{30,000}{1.01^{10}}\approx 27,158.61$
