Post the exact question - completely.

Your textbook should have example problems like this.

What is the chapter heading for these problems?

I Get The Examples But The Are Totally different From This Problem!

The Chapter Heading Is Exponential Growth And Decay!

In the example problems for this chapter,

What is the equation that is used (mostly)?

What does each term mean in that equation?

Also do you know - what does compounding interest mean?

And 4% Is The Annual interest

use ^ to represent "power" : y = a*b^x

f(uture) = p(resent) * [1 + i(nterest rate)]^n(umber of periods)

f = p(1 + i)^n

Relate that to your equation.

If you're still stuck, you need classroom help.
