Sophie earned a grade of 72% on her multiple choice history final that had a total of 200 problems. How many problems on the final exam did Sophie get wrong?

Respuesta :

Answer:

56 questions.

Step-by-step explanation:

percent got wrong = 100% - percent got correct.

percent got correct = 72%

percent got wrong = 100%-72% = 28% or 0.28

questions got wrong = total questions * percent got wrong.

total questions = 200

questions got wrong = 200*0.28 = 56 questions

Therefore, Sophie got 56 questions wrong.
