P = 20 000
T = 15
K = 6 (semi annually)
r = 0.05
i = 0.05/6 = 5/600
n = 6(15) = 30
Now , Substituting the values to the Formula
[tex]A= P(1+i)^n \\ A= 20 \: 000(1+ {\frac{5}{600} })^{30} \\ A= 20 \: 000( \frac{600}{600} + \frac{5}{600} )^{30} \\ A= 20 \: 000( \frac{605}{600} )^{30} \\ A= 20 \: 000(1.282695963) \\ A= 25 \: 653.91927 \\ \boxed{A= 25 \: 653.92}[/tex]
