Answer:
[tex]3x\geq 45[/tex]; At-least 15 questions.
Step-by-step explanation:
Let x represent the number of questions you need to answer correctly..
We have been given that each question is worth 3 points. The points earned from answering x right questions would be [tex]3x[/tex].
Since we need at-least 45 points to win the game, so points earned from answering x questions would be greater than or equal to 45. We can represent this information in an equation as:
[tex]3x\geq 45[/tex]
[tex]\frac{3x}{3}\geq \frac{45}{3}[/tex]
[tex]x\geq 15[/tex]
Therefore, you need to answer at-least 15 questions correctly to win the game.
