Answer:

50

Explanation:

  1. Starting point: -50
  2. An answer that is correct: add the required amount of points to your score
  3. An answer that is incorrect: subtract the required amount of points from your score
  4. 150 point question correct: -50 + 150 = 100
  5. 250 point question incorrect: 100 - 250 = -150
  6. Four 50 point questions correct: -150 + (50 Ă— 4) = -150 + 200 = 50

I hope this helps!
