The number of points added for r right answers is 12r. The number of points taken away for w wrong answers is 4w, so Olga's total points will be

... 12r -4w

To win, she needs this number to be more than 400. Your inequality is ...

... 12r -4w > 400

Answer:

12R-4W > 400

Step-by-step explanation:

You have to use capital R and capital W otherwise the answer is incorrect. Lowercase r and lowercase w will get you the answer wrong so it is

12R-4W > 400
