Brooke earned the following scores on four history tests: 88, 86, 92, and 84. Brooke wants to have an average score of at least 85 after the fifth test. Write and solve an inequality to find the possible scores that she can earn on her fifth test in order to meet her goal. The greatest score that she can earn on a test is 100. Is it possible for her to have an average score of 90 after the fifth test?

Do I do 85 ≤ (x + 350) / 5?
