A science test, which is worth 100 points, consists of 24 questions. Each question is worth either 3 points or 5
points. If x is the number of 3-point questions and y is the number of 5-point questions, the system shown
represents this situation
x + y = 24
3x + 5y = 100
What does the solution of this system indicate about the questions on the test?

O The test contains 10 three-point questions and 14 five-point questions
O The test contains 14 three-point questions and 10 five-point questions,
O The test contains 20 three-point questions and 8 five-point questions
