Earl answered 2 more math questions correctly than Anna did. Anna answered 3 fewer questions thatn Juanita did. Juanita answered 21 questions correctly. How many questions did Earl answer correctly? Could someone explain how to get the answer. Thanks.
Juanita answered 21, and Anna answered three fewer than this, so Anna must have answered 18. Earl answered two more than Anna, so Earl must have answered... what?
20
To find out how many questions Earl answered correctly, we can break down the problem into smaller parts using the information given in the question.
First, we know that Juanita answered 21 questions correctly.
Next, we are told that Anna answered 3 fewer questions than Juanita did. So, Anna answered 21 - 3 = 18 questions correctly.
Lastly, Earl answered 2 more questions correctly than Anna did. If Anna answered 18 questions correctly, then Earl answered 18 + 2 = 20 questions correctly.
Therefore, Earl answered 20 questions correctly.
