Answer:
B. The test contains 10 three-point questions and 14 five-point questions.
Step-by-step explanation:
x + y = 24
3x + 5y = 100
x + y = 24
y = 24 -x
Substitution(plug in) 3x + 5y = 100
3x + 5(24 -x) = 100
3x + 120 -5x = 100
-2x = -20
x = 10, given that value, plug x in the original equation
x + y = 24
10 + y = 24
y = 14
x = 10, y = 14
x is 3p and y is 5p
Therefore, the answer is B.
