Wilma saves $12,000 at the end of every six months for 10 years. assume 10% compounded semiannually and find the present value. $73,734.84 $137,547.52 $195,589.79 $149,546.52

Here we use the formula for compound interest given by:
A=p(1+r/100*n)^(nt)
where:
A=amount=
p=principle=12000
r=rate=0.1
n=# terms=2
t=time=10 years
thus;
A=12000(1+0.1/2)^(2*10)
A=31839.6
