+23252 Because she will get 1.5 points for each question left unanswered and she leaves 3 questions unanswered,
she will receive 3 x 1.5 points = 4.5 points.
To get at least 100 points, she will need 100 - 4.5 points = 95.5 points on the first 22 questions.
Since she gets 6 points for each correct answer, she will need 95.5 / 6 = 15.92 correct answers --->
she will need 16 correct answers.
16 x 6 = 96 points + 4.5 points = 100.5 points.
