Suppose an individual wants to have $200,000 available for her child's education. Find the amount that would have to be invested at 12%, compounded continuously, if the number of years until college is: 1 ) 6 years 2 ) 15 years 3) Does leaving the money invested twice as long mean that only half as much is needed initially? Explain why or why not. please help me, I'm trying to study for the final exam which will take place tomorrow. thank you. 2. The first is an excellent exploration. Try this:$\displaystyle 2000*\left(1\;+\;\frac{0.08}{m}\right)^{4*m}\$

What is it for m = 1? Annually?
What is it for m = 2? Semi-Annually?
What is it for m = 4? Quarterly?
What is it for m = 12? Monthly?
What is it for m = 52? Weekly?
What is it for m = 365? Daily?
What is it for m = 365*24? Hourly?

Is there a limit to the values you are getting? Let's remember a little calculus and track it down.
