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.
