(c)43 times
Step-by-step explanation:
<u>Part A</u>
The paper's thickness = 0.05mm
When the paper is folded, its width doubles (increases by 100%).
The thickness of the paper grows exponentially and can be modeled by the function:

<u>Part B</u>
<u />
<u />
<u />
<u>Part C</u>
If the thickness of the paper, g(n)=384,472,300,000 mm
Then:

You must fold the paper 43 times to make the folded paper have a thickness that is the same as the distance from the earth to the moon.
