Answer: Alyssa did not get an A.
Explanation:
Alyssa took a math test with 20 questions and she answered 16 questions correctly. It means that the percentage of the questions that she answered correctly is
16/20 × 100 = 80%
In order to get an A, she needs to answer at least 90 percent of the questions correctly. Therefore, Alyssa did not get an A.
