In a 100-item exam, Lowella got 35% of the questions correctly. Pamela got 20% more correct answers than Lowella and Mandy got twice Pamela's score. What is Mandy's score? Let's be accurate as possible.
Lowella got 100 x 35 / 100 = 35 correct answers. Pamela got 35 x 20 / 100 = 7 more correct answers than Lowella. So, Pamela got 35 + 7 = 42 correct answers. Thus, Mandy got 42 x 2 = 84 correct answers.
The answer: 84.
