You can put this solution on YOUR website! Terry did all 25. Questions on the test and got and 85% scores are computed by giving 4 poins for each right answer and subtractinf 1 point for each wrong answer how many problems did terry get right or wrong.
Equations:
r + w = 25 questions
4r- w = 85 points
----------------
Add and solve for "r"::
5r = 110
right = 22 (# of correct answers)
wrong = 25-22 = 3 (# of wrong answers)
