Using the given property, we conclude that:
f(4) = 8
<h3>
What is the value of f(4)?</h3>
We know that our function has the property:
5*f(x) = f(5*x)
Now, we also know that:
f(20) = 40
Notice that we can rewrite:
f(20) = f(5*4)
Using the above property, we know that:
f(20) = f(5*4) = 5*f(4) = 40
Using the last part:
5*f(4) = 40
f(4) = 40/5 = 8
f(4) = 8

Answer:
The average score is 73
Step-by-step explanation:
Your average score is the sum of each of your tests scores multiplied by the weight of the test.
We have that:
You scored 90 on the midterm
The midterm is worth 30%
You scored 60 on the final
The final is worth 50%
You scored 80 on the class project
The class project is 20%
Average score:
A = 90*0.3 + 60*0.5 + 80*0.2 = 73
C is the missing reason in this proof.
