Ateacher 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 what was marci's score

To figure this out, you have to figure out what Donovan scored.
Just divide his score (39 ÷ 50) and get 0.78.

Since we already knew this, we can figure out Marci's score. Since she score 88%, we can assume she scored somewhere in the 40's.
Once you figure out what her score was out of 50, divide it.

Your equation should look like this: 44 ÷ 50 = 0.88

This means that Marci answered 44 questions out of 50 questions correctly. (44/50)

What are the options
