To find the minimum number of correct answers Jenny obtained, we need to consider the scenario with the lowest possible score.
Let's assume that Jenny answered all 19 questions incorrectly. Since each incorrect answer results in a deduction of 3 points, her total score would be -57 (19 questions * -3 points per incorrect answer).
However, we know that her total score is above 32. Therefore, Jenny must have answered at least one question correctly.
To determine the minimum number of correct answers, we need to find the highest possible score that is still above 32. Since 3 points are awarded for a correct answer, we can calculate the minimum number of correct answers as follows:
Minimum number of correct answers = (Total score - Lowest possible score) / Points per correct answer
Minimum number of correct answers = (32 - (-57)) / 3
Minimum number of correct answers = 89 / 3
Minimum number of correct answers ≈ 29.67
Since we cannot have a fraction of a correct answer, Jenny must have answered at least 30 questions correctly in order to have a total score above 32.
