10) Jackson’s scores on the first four algebra quizzes are 79, 88, 95, and 71. What score must he earn on the fifth quiz to earn
an average quiz score of 85?
1 answer:
Based on the given information, let x represent the grade for the fifth quiz.
(79+88+95+71+x)/5=85
(333+x)/5=85
333+x=425
x=92
Jackson would have to earn a 92 on his fifth quiz to earn an average of 85.
