Okay! In order to find 8 groups of .32 you'd simply divide them. So:
[.32 ÷ 8] = .04
To check you multiply:
[8 x .04] = .32.
The answer is .04
Let
x------> the number of multiple choice question
y------> the number of free response question
we know that
-----> equation A

-----> equation B
Substitute equation B in equation A
Find the value of x


therefore
<u>the answer is</u>
the number of multiple choice question are 
the number of free response question are 
Y² + 8y + 15
since 8 and fifteen are positive, that means your factors are going to be positive
(y + )(y + )
What are the factors of 15 that add up to 8?
-128y^2 x y^1 +2 = -128y^3
