See Canvas for more details. Assume a machine during its initial testing phase produces $10$ gadgets a day. After $10$ days of testing $($starting on day $11),$ it begins to ramp up$,$ producing $1$ more gadget per day $(11$ gadgets on day $11,12$ on day $12,$ etc$).$ On day $50$ it reaches full speed, where it continues to run until on day $101$ it stops producing gadgets. Write a program named how$\_$many$\_$gadgets.py that reads in a day $($as a number$)$ from the keyboard and reports the total number of gadgets produced from the initial testing phase up to and including the day entered.

Example output $($using input $3)$:

Please enter a positive value for day: $3$

The sum total number of gadgets produced on day $3$ is $30$

Example output $($using input $-1)$:

Please enter a positive value for day: $-1$
