Question

Jackie scored 82 and 88 on her first two quizzes. Write and solve a compound inequality to find the possible values for a third quiz score that would give her an average between 80 and 85, inclusive.
80 ≤ the sum of 82 + 88 + n over 3 ≤ 85; 70 ≤ n ≤ 85
70 ≤ the sum of 82 + 88 + n over 3 ≤ 85; 80 ≤ n ≤ 85
80 < the sum of 82 + 88 + n over 3 < 85; 70 < n < 85
82 ≤ the sum of 80 + 85 + n over 3 ≤ 88; 70 ≤ n ≤ 85
