A teacher is creating an assignment worth 70 points. The assignment will consist of questions worth 1 point and questions worth 3 points. Which equation represents this situation, where x represents the number of 1-point questions and y represents the number of 3-point questions?
Correct answer: D. x + 3y = 70
- A. 4xy = 70
- B. 4(x + y) = 70
- C. 3x + y= 70
- D. x + 3y = 70
Explanation
Choice D is correct. Since x represents the number of 1-point questions and y represents the number of 3-point questions, the assignment is worth a total of 1.x + 3.y or x + 3y, points. Since the assignment is worth 70 points, the equation x + 3y = 70 represents this situation.
