Javier needs to earn at least an 80 in college algebra only exam scores are used to calculate his grade currently he has scored a 73,71 and 82 this semester with the semester exam counting twice what is the minimum score needed on the semester exam to earn an 80 or

The minimum score needed on the semester exam to earn an 80 by Javier is 87.

Step-by-step explanation:

The scores he has scored in the papers  = 73, 71 and 82

Let us assume the score Javier scores in the semester exam = p

The average of the total marks = 80

or, p = 87

Hence,  the minimum score needed on the semester exam to earn an 80 by Javier is 87.
