Answer: Marna has to answer more than 16 answers to win the game.


Step-by-step explanation:

Le 'x' be the number of correct answers.

If Marna is getting -5 points each time she guess the correct answer.

Then the total points she get after x correct answers= -5x

If to win the game, Marna  must have a score of less than -80 points.

⇒[tex]-5x<-80[/tex]

If we multiply (-1) on both sides the inequality will reverse

[tex]5x>80[/tex]

Divide both sides by 5, we get

[tex]x>16[/tex]

Marna has to answer more than 16 answers to win the game.
