Answer:

4%

Step-by-step explanation:

The change in  her score in percentage points for each question she gets incorrect is 4%.

Using this formula

Change in score percentage=(100%-Scores %)/Number of missed questions

Where:

Scores %=72%

Number of missed questions=7 questions

Let's plug in the formula

Change in score percentage=(100%-72%)/7

Change in score percentage=28%/7

Change in score percentage=4%

In conclusion, the change in  her score in percentage points for each question she gets incorrect is 4%.

Answer:

For every question she missed had 4% affect on total score.

                                    step-wise explanation:

missed question(%):

total percentage - scored percentage

100% - 72%

28%

She missed 7 questions:

7 questions ↔ 28%

1 question ↔ [tex]\frac{28}{7}[/tex]%

1 question ↔ 4%
