0.500000000000000000000000 = 1 / 2 I hoped I helped you all u got to do is just use your calculator.
A=P(1+r/n)^(tn)
n=number of times per year compounded
A=amount
P=principal inveseted
r=rate in decimal
t=time in years
so
we want A=30000
r=12.4%=0.124
t=15
monthyl means n=12
30000=P(1+0.124/12)^(15*12)
solve for P
easy, just divide both sides by (1.01033)^180
4714.97=P
that much must be invested
