The final grade in an algebra course is based on a weighted average - homework counts 10%, quizzes count 15%, tests count 50%, a
nd the final exam counts 25%. A student has a homework average of 67, a quiz average of 62, and a test average of 71. What minimum score does the student need on the final exam to get at least a 70 for the final course grade?
To find the minimum score a student needs to score on the final exam to earn at least a 70 for the final course grade, we will multiply the student's scores with their respective weight-age.
Supposing the minimum score in the final exam to be x, we can write an equation:
