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 10 percentage points higher than Donovan's. What was Marci's score? (88%) How many more questions did Marci answer correctly?

Verified Answer :

The correct answer is that Marci scored 5 more questions correct than
Danovan. It is relatively simple to answer this equation. The first step simply involves figuring out how Donovan did, and to do so you just
need to divide his scores (39/50) to get the number 0.78. With this
information, we can then work out Marci's score. We know that she scored
88%, which means she must have scored somewhere in the 40s. Once you've
figured out the score out of 50, you then just need to divide it as you
did with Donovan[s score. You will get to 44/50, which will give you
the answer of 0.88.
