Pb$.2$

A$)$ Write a function that calculates the Final Grade $($Name it my$\_$FG$).$ The function should accept the Homework grade $($name it HW$),$ class work grade $($CW$),$ midterms grade $($MT$),$ and final exam grade $($FE$),$ all out of $100,$ and calculate the final grade $($FG$)$ based on the following:

$FG=0\mathrm{.}25*HW+0\mathrm{.}10*CW+0\mathrm{.}35*MT+0\mathrm{.}3*FE$

Make sure that the function file contains enough comments and description of the steps.
