There were balls but we took
balls out, so there are now
balls. We add
balls and now we have
balls.
The program that computes this (I will use python as language has not been specified is the following):
n, a, b = int(input()), int(input()), int(input())
print(f"There are {n-a+b} balls in the box")
# Hope this helps
Answer:
def finalGrade(scoresList):
""" Function that finds the final grade """
hw1_weighted = float(scoresList[0])/10 * 0.05
hw2_weighted = float(scoresList[1])/10 * 0.05
mid_weighted = float(scoresList[2])/100 * 0.40
fin_weighted = float(scoresList[3])/100 * 0.50
final_grade = (hw1_weighted + hw2_weighted + mid_weighted + fin_weighted) * 100
return final_grade

Explanation:
This program was implemented with python programming language.
This program will read the scores from the CSV file, pass the scores as a list to the finalGrade function, and display the resulting final grade, along with the student's name.
