Answer:

Sandra's final score is -5\frac{1}{4}.

Step-by-step explanation:

It is provided that each question Sandra answers incorrectly changes her overall score by -3/4 points.

That is, for every incorrect answer Sandra looses 3/4 points.

At a moment Sandra's overall score was -4\frac{1}{2} points.

And then she answered the last questions incorrectly.

Compute the final score as follows:

Final score = Sandra's overall score - \frac{3}{4}

                   =-4\frac{1}{2}-\frac{3}{4}\\\\=-\frac{9}{2}-\frac{3}{4}\\\\=\frac{-18-3}{4}\\\\=-\frac{21}{4}\\\\=-5\frac{1}{4}

Thus, Sandra's final score is -5\frac{1}{4}.
