A teacher gave a test with 50 questions, each worth the same number of points. Donovan got 39 out of 50 questions right. Marci's
score was 90%.
How many more questions did Marci answer correctly?

1 answer:
So Marci's sore was 45 because every percent has to be out of 100 so to get it to 50 you divide by two so 90 / 2 = 45. And 45-39 = 6
Marci got 6 more correct then Donovan.

This should be answered with the mean. The lower the mean, the lower the score it took to get the mean. So B is the answer.
