Final answer:
To calculate Ned's points, multiply the number of questions he got wrong by 5 to find the points lost and add 8 points for the bonus question. Without knowing the number of incorrect answers, the exact score cannot be determined.
Step-by-step explanation:
The student is asking how many points Ned received or lost on a test with a bonus question. To determine this, we need to calculate the number of questions Ned answered incorrectly and the points gained from the bonus question.
If Ned took a test with 20 questions and he loses 5 points for each incorrect answer, we'll describe how many questions he got wrong as 'x'. Then the points lost would be 5x because he loses 5 points for each wrong answer.
Ned also earned 8 points for answering a bonus question correctly. The overall score would be the bonus points minus the points lost from any wrong answers. If we represent the overall points Ned received or lost as 'P', the equation would be P = 8 - 5x.
Unfortunately, without knowing the exact number of questions Ned got wrong, we cannot provide a specific number of points for his overall score.
