The age of an artifact can be calculated by the technique of radio-carbon dating

a) Create a python function that will return the age of an artifact in years given it's percentage of C14 remaining.

b) Create a function that returns 2 lists containing percent of C14 remaining and the age of the artifact, respectively.

c) Write another function to write the values in a file-where each row contains percent of remaining percentage of C14 and the age of the artifact in years separated by a comma, name your output file as "Carbon Dating.txt"
