Answer:
Score with 5 questions wrong = 40 points
x questions wrong = 50 - 2x points
Score with a question wrong = 48 points
Step-by-step explanation:
Total points = 50 points
Points per question = 2 points
Number of questions = Total points / Points per question
= 50/2
= 25 questions
What would be Nasim's test score (out of 50) if he got 5 questions wrong
= Total points - 5 questions * 2 points
= 50 - 5(2)
= 50 - 10
= 40 points
Score with 5 questions wrong = 40 points
What would be his score if he got x questions wrong?
= Total points - x questions * 2 points
= 50 - x(2)
= 50 - 2x
Where x = number of questions
x questions wrong = 50 - 2x points
Score with a question wrong
= Total points - 1 questions * 2 points
= 50 - 1(2)
= 50 - 2
= 48 points
Score with a question wrong = 48 points
