Final answer:
To solve for the number of questions on the exam, you can use the equation x * 4 = 76, where x represents the number of questions. Dividing both sides of the equation by 4, you find that there were a total of 19 questions on the exam.
Step-by-step explanation:
To solve for the number of questions on the exam, we can set up an equation using the given information. Let's let 'x' represent the number of questions. Since each question is worth 4 points and the total number of points is 76, we can write the equation as:
x * 4 = 76
To solve for 'x', divide both sides of the equation by 4:
x = 76 ÷ 4 = 19
Therefore, there were a total of 19 questions on the exam.
