After hearing plenty of stories about "fake" beggars, I decided to mathematically figure out how much one could earn by begging an entire year.
How I got there...
I am using a bell curve function to find the estimates of earning throughout each day.
Then I use a wave function to find daily earning estimates throughout the week.
After using these two functions to transform the daily earnings, I calculate the summation of an entire year.
I realize that I could use much better functions for estimation, but this was just some quick research.
Finally, if you could find a way to earn $20/hr, you could make $39,030.67 annually according to this formula.
