Lyssa and Precious took an English proficiency exam. Lyssa answered 20% of the items incorrectly. Precious got 12 mistakes. How many more correct answers did Lyssa get than precious if there were 75 items in the exam? Give me reasons, before answering the question
Lyssa got 75 x 20 / 100 = 15 mistakes. Lyssa's score is 75 - 15 = 60. The score of Precious is 75 - 12 = 63. Thus, Lyssa got 63 - 60 = 3 more correct answers than Precious. So the final answer is 3.
