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
K = 4a+9ab
k = a(4+9b)
k/(4+9b) = a
a = k/(4+9b)
None of the answer choices match what I got, so I'm thinking there's a typo. Perhaps choice A is supposed to say a = k/(4+9b) since that seems like the closest
8 Is you're answer! hope that i helped!
That would be the first choice:
5^0 = 1 , 5^1 = 5, 5^2 = 25 and so on up to 5^4 = 625
