A student scored 83 and 91 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 85 and 90, inclusive. (1 point)
85 ≤ ≤ 90; 81 ≤ n ≤ 96
85 ≤ ≤ n; –2 ≤ n ≤ 3
90 ≤ ≤ 85; 96 ≤ n ≤ 81
83 ≤ ≤ 90; 73 ≤ n ≤ 94
