Help with an Equation

[themattman]

Hi everyone, I need some help. I was asked to create an equation that would allow me to calculate the amount of money one would have if they started with a penny and it was doubled for a certain amount of days. I figured that out amount = .01 * (2 ^ #days)

Now I need to figure it our with a nickel. If you start with a nickel and double it every day. How do yo figure that out? Any help would be much appreciated!

I figured that out

amount = .01 * (2 ^ #days)

I'm stumped about how you were able to "figure it out" with a penny but are unable to do the same thing with a nickel.

Will you please briefly explain your reasoning with the penny, so that I might determine why you're stuck with the nickel?

Also, please tell me what the mathematical expression 2^5 means to you.

Cheers ~ Mark :cool:

Ok I just realized its the same thing just change .01 with .25. It just didn't seem to be coming out right but must have been doing some thing wrong.

You meant to type 0.05 instead of 0.25, yes?
