Answer:
$67415.73
Step-by-step explanation:
we know that
FV = P(1+r/n)^nt
where FV = future value
P= Present values =$18000
r= rate of interest =9%
n= year. = 15 year
here , the interest is compounded semi-annually
this means n= 30 , r= 4.5%
plugging the value we have
FV = 18000(1.045)^30= $67415.7264= $67415.73
