Question

Mia is taking a multiple choice test with a total of 50 points available. Each question is worth exactly 2 points. What would be Mia's test score (out of 50) if she got 3 questions wrong? What would be her score if she got x questions wrong?

Answer 1

Answer:

Mia's test score is 44 if she got 3 questions wrong.

Mia's test score is (50-2x) if she got x questions wrong.

Step-by-step explanation:

It is given that, Mia is taking a multiple choice test with a total of 50 points available. Each question is worth exactly 2 points.

If she got 3 questions wrong, then

Deducted marks $=2\times 3=6$

Marks obtained by Mia = Total marks - Deducted marks

                                      $=50-6$

                                     $=44$

So, Mia's test score is 44 if she got 3 questions wrong.

If she got x questions wrong, then

Deducted marks $=2\times x=2x$

Marks obtained by Mia = Total marks - Deducted marks

                                      $=50-2x$

So, Mia's test score is (50-2x) if she got x questions wrong.
