Answer:
OPTION D: Between 7.33 and 7.34
Step-by-step explanation:
The maximum score is 10. So, the marks for her mistakes would be deducted from 10.
Since, Maya has made 8 mistakes and each mistake costs her [tex]$ \frac{1}{3} $[/tex] marks.
For 8 mistakes, she would lose [tex]$ 8 \times \frac{1}{3} = \frac{8}{3} $[/tex] marks.
Hence, the total marks she would get would be: [tex]$ 10 - \frac{8}{3} = \frac{30 - 8}{3} = \frac{22}{3} $[/tex]
= 7. 333... (approx...)
Hence, the value should be between 7. 33 and 7 . 34.
OPTION D is the correct answer.
