How to evaluate an exponential function modeling a real life situation

The video tutorial explains how to calculate the amount of carbon left in a substance over time using an equation. It begins by defining variables for carbon amount and time, then demonstrates calculating the initial carbon amount when time is zero. The tutorial proceeds to calculate the remaining carbon after 10,400 years, emphasizing the importance of using exact values in calculations.

Explain the significance of the number E in the carbon decay equation.

How much carbon is left after 10,400 years according to the calculations?
