Answer:
The test contains 10 three-point questions and 14 five-point questions.
Step-by-step explanation:
We are given that A science test, which is worth 100 points, consists of 24 questions. Each question is worth either 3 points or 5 points
System of equations:
--a
--b
Where x denotes x is the number of 3-point questions and y is the number of 5-point questions
Now solve equation a and b by substitution method
Substitute the value of x from a in b
⇒
⇒
⇒
⇒
⇒
⇒
Substitute the value of y in equation a to get the value of x
Thus 10 is the number of 3-point questions.
14 is the number of 5-point questions.
Thus Option 2 is correct.
The test contains 10 three-point questions and 14 five-point questions.
