One can miss up to 24 questions and still achieve an 80% score.
In order to calculate the points each question is worth and determine how many questions you can miss while maintaining an 80% score.
To find the points each question is worth, we divide the total points by the number of questions. Let's assume the test is out of 100 points, which is a common scale. Therefore, each question would be worth or approximately 1.05 points.
Now, let's determine how many questions you can miss while still achieving an 80% score (which is 80 out of 100 points). We'll set up an equation to solve for the maximum number of questions you can miss, denoted by "x":
To solve for "x," first, we'll simplify the equation:
Next, we'll isolate "x" by multiplying both sides by 95:
Now, isolate "-100x" by subtracting 7600 from both sides:
Finally, divide both sides by -100 to solve for "x":
So, you can miss up to 24 questions and still achieve an 80% score.
