final grade:42

Step-by-step explanation:

Given function:

  • 13 of 31..

Subtract the two terms:

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..
