write an inequality that represents the number of right answers (r) and wrong answers (w) olga can give to win the contest.

Answer 1

12R-4W > 400

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

Answer 2

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
