Step-by-step explanation:
Consider the provided table.
On the test was worth an equal number of periods.
Let x is the number of points of each question.
Christopher answer six questions incorrectly and the score of Christopher is -24 which can be written as:
6x = -24
x = -4
Here, minus sign represents the lost of points.
For each wrong question student will get -4 points.
Now consider the table.
Michael lose -12 points.
-4 × 3 = -12
Thus, Michael answered 3 questions incorrectly.
Nythia lose -16 points.
-4 × 4 = -16
Thus, Nythia answered 4 questions incorrectly.
Raul lose -4 points.
-4 × 1 = -4
Thus, Raul answered 1 questions incorrectly.
Tonya lose -28 points.
-4 × 7 = -28
Thus, Tonya answered 7 questions incorrectly.
The another student answered 9 questions incorrectly.
-4 × 9 = -36
Thus, the student lose -36 points.
