Q: In a spelling contest held in her school, Drew got 20 questions correct, winning her the competition. She got six questions wrong, and her competitor Carla got 14 questions correct, and twice as many questions wrong as the number of questions Drew got wrong. If each competitor was asked a different question, how many questions were asked in the competition?
A: Since Drew got 20 questions right and 6 wrong, she was asked 20 + 6 = 26 questions. Carla got twice as many questions wrong as Drew got, a total of 2 * 6 = 12 questions wrong. The total number of questions that Carla was asked is 12 + 14 = 26. Altogether, there were 26 + 26 = 52 questions that were asked in the contest. The answer is 52.
