Answer 1

7

Explanation:

Just notice that correct answers are whole numbers.

And, to win the game,Maria must have a score less than -80, it means she needs to score al least -85 ( it can not be -81, -82.. because 1 correct answer score -5, only multiples of -5 are accepted)

So, we take:
`(-85)/(-5)` = 7 correct answers to win the game.
