To model Janna's situation in an inequality, we can represent her current score and the points she earns from correctly answering questions.
Let \( x \) be the number of correct answers Janna gives. Each correct answer gives her 2 points, so her total score after answering \( x \) questions would be \( 50 + 2x \).
Janna needs her score to be greater than 68 points to advance to the next round. We can set up the inequality as follows:
\[ 50 + 2x > 68 \]
This inequality shows the relationship between the number of correct answers \( x \) and the points required to advance to the next round.
