Find out how many points each question is worth.

Question

Jan received a -22 on her exam. She got 11 questions wrong out of 50 questions. How much was Jan penalized for each wrong answer?

Answer 1

total score = -22

let x = # of points for a right answer

let y = # of points for a wrong answer

the -22 = 39x + 11y

if this is the only info you have then one possible answer for this parametric equation is

x = 0, y = -2 for each wrong answer

that 0 points for right answer and -2 points for a wrong answer

(another possible answer is each right answer gets 11 points and each wrong answer gets -41 points - a ridiculous scoring system but one that produces the correct answer given the parameters of the stated problem.)
