Question

Jamie took a test. She got 31 correct, and 13 incorrect. Find the percentage of incorrect answers to correct answers. Explain with all steps.

Answer 1

final grade:42

Explanation:

Given function:

• 13 of 31..

Subtract the two terms:

• 
  `31-13=18`

Divide 100 by 31:

• 
  `100*31=3.22`

Multiply result by 18:

• 
  `3.22`·
  `18=58`

Subtract 100 by 58:

• 
  `100-58=42`

Therefore, Jamie got 42% of his test wrong and 58% would be his final grade..
