Four years ago you invested some money at $10\%$ interest. You now have $\$439.23$ in the account. If the interest was compounded yearly, how much did you invest 4 years ago?

 

Given that $f(x) = (\sqrt 5)^x$, what is the range of $f(x)$ on the interval $[0, \infty)$?

PV = FV / [1 + R]^N

PV =439.23 / [1 + 0.10]^4

PV =439.23 / [1.10]^4

PV =439.23 /   1.4641

PV =$300 - what you invested 4 years ago @ 10% APR.
