Answer: B) 10 three-point questions and 14 five-point questions
<u>Step-by-step explanation:</u>
x represents three-point questions
y represents five-point questions
3x + 5y = 100 → 1(3x + 5y = 100) = 3x + 5y = 100
x + y = 24 → -3(x + y = 24) = <u> -3x -3y = -72 </u>
2y = 28
y = 14 (five-point questions)
x + y = 24
x + 14 = 24
x = 10 (three-point questions)
