First, name your variables,
W-Weekly problems
Q-quizzes
T-Tests
R-Reflections/Reactions
F-Final
Maximum possible: W%2BQ%2BT%2BR%2BF=100
Your Total Grade: 8%2B20%2B23%2B5%2BF=56%2BF
In order to achieve a B,your total grade must be at least 80 or higher.
56%2BF%3E=80
56-56%2BF%3E=80-56 Additive identity of 56 applied to both sides.
F%3E=24Final answer.
You need at least 24 points on your final to get a B in the course.
