Given :
Peyton is taking a multiple choice test with a total of 20 points available. Each question is worth exactly 2 points.
To Find :
Peyton's test score (out of 20) if she got 4 questions wrong.
Solution :
Total numbers of questions are 20/2 = 10 questions.
Points after getting 4 questions wrong :
P = 2( 10 - 4 )
P = 12
Therefore, her score after getting 4 questions wrong is 12.
Hence, this is the required solution.
