Given the following function header and docstring, complete the function$$s body. You

may use Python$$s built$-$in functions in your solution.

def final$\_$grade$($final: float, midterm: float, bonus: float$)->$ float:

$"""$Return the grade in a course, given the scores in the final and

midterm exams and a bonus score.

The final exam is worth $80\%,$ the midterm $20\%,$ and the bonus is worth $10\%.$

If the weighted average of the final exam and the midterm exam is below

$60$ out of $100,$ the final grade is the weighted average. Otherwise, the

weighted bonus is added, giving a maximum score of $110.$ The final grade

is the minimum of $100$ and the score calculated using the bonus.

Preconditions: all parameter values are between $0$ and $100.$

$>>>$ final$\_$grade$(40\mathrm{.}0,0,100)$

$32\mathrm{.}0$

$>>>$ final$\_$grade$(100,40\mathrm{.}0,100)$

$98\mathrm{.}0$

$>>>$ final$\_$grade$(100,100,100)$

$100$
