Answer:

$29,606

Explanation:

Future Value(FV)=PV×(1+r)^n−1/r

Where,

PV = present value = X

r = rate of interest =16%=16/100= 0.16

n=Number of years = 4

Future Value =FV= $150,000

Future Value(FV)=PV×(1+r)^n−1/r

150,000=X∗(1+0.16)^4−1/0.16

150,000=X*(1.16)^4-1/0.16

150,000=X*1.81063936-1/0.16

150,000=X∗0.81063936^0.16

150,000=X∗5.066496

X=150,000/5.066496

X=29,606.26

Approximately

X=$29,606
