a math test consist 20 multiple choice questions. 3 points are awarded for a correct answered. 1 point is deducted for a wrong answer. no points are awarded or deducted for an answered questions. jenny attempted a total of 19 questions and her total score is above 32. find the minimum number of correct answers she obtained?
3x - 1(19-x) >= 32
A pupil answered 20 quiz questions and scored 60 points.
For each correct answer, 5 points were given.
For each wrong answer, 3 points were deducted.
How many questions did the pupil answer correctly ?
To find the minimum number of correct answers Jenny obtained, let's assume she answered all the questions correctly.
In that case, she would have scored 3 points for all 19 questions attempted, resulting in a total score of 57 (19 questions * 3 points/question).
We know her total score is above 32, so let's try to find the minimum number of correct answers such that her score is at least 33 (since 33 is greater than 32).
Since there are no points deducted for unanswered questions, we can find the minimum number of correct answers using the following equation:
3 * Number of Correct Answers ≥ 33
Dividing both sides of the equation by 3, we get:
Number of Correct Answers ≥ 11
Therefore, the minimum number of correct answers Jenny obtained is 11.
