Video Summary

In a quiz of 20 questions, Eric scores 100 points with each correct answer giving 7 points, incorrect answers deducting 4 points, and blank answers scoring zero. Out of a possible 140 points, Eric's incorrect answers and blanks caused a 40-point deficit. Incorrect answers reduce the score by 11 points each (7 lost for correctness and a 4-point penalty), and blanks result in a 7-point loss (only missing out on potential points). Solving the equation 11I + 7B = 40 with the constraint yields B = 1, meaning Eric left one question blank.
