Answer:
final grade:42
Step-by-step explanation:
Given function:
- 13 of 31..
Subtract the two terms:
- [tex]31-13=18[/tex]
Divide 100 by 31:
- [tex]100*31=3.22[/tex]
Multiply result by 18:
- [tex]3.22[/tex]·[tex]18=58[/tex]
Subtract 100 by 58:
- [tex]100-58=42[/tex]
Therefore, Jamie got 42% of his test wrong and 58% would be his final grade..
