I can get to the point of the -36.2e^-1.056 but I absolutely can not figure out how to come up with the final answer. I know it is something I am missing. Any help would be appreciated. Thank you.

Cannot see your picture properly without a microscope - and do not have one of those handy!!

Post a "bigger" picture or "transcribe by hand" to the screen.

After copying the image to a word-file and expanding it - I understood the question.

Use a calculator (or a spreadsheet like MS-Excel) - to calculate e-1.056 then multiply it with -36.2

That's it....

The problem i am having is how to solve for e. I am drawing a total blank on that.

Solve for e? In this problem, e is a constant = \(\displaystyle \displaystyle \sum_{i=0}^{\infty}\dfrac{1}{i!}.\)

If you are asking how to get a good approximation to e on your calculator, that will depend on your calculator. Does it have an ex button? On my calculator it is the inverse of the ln button.

You do not solve for 'e'. It is an irrational constant number (≈ 2.71828183) - something like π. (watch http://www.youtube.com/watch?v=ZPGHuuk2bKw)

Like π the value of e should be precoded into your calculator.

What type of calculator are you using?

Put up a clear picture of your calculator.

I'll tell you which buttons to push.

I am using a casio fx 260. I dont have it with me right now since I am not home. I have several problems on my work that have an exponential to (t) for time and have been unable to figure out what i am inputting wrong on the calculator to come up with the correct answer. I am fine till i get to the final part of the equation and then I have to be inputting something incorrectly.

Don't you have a User's Manual - read it!

If your calculator looks like this

To get ex

Punch in value of x

press shift, followed by pressing the 5th button on the first row ("ln").

You should get the answer.
