Answer:
1.5, final answer.
Step-by-step explanation:
When x=20, y=5.
When x=6, y=?
5/20 equals 25%.
x/6 should also equal 25%.
x=6/4
x=1.5
It is a decrease because it went down in cost.
To find percent:
Find difference from original amount to present amount.
So we do 4.11-2.92
=1.19
Now find the percent:
1.19/4.11 is about 28%
28% change.
Someone plz double check this answer.

So if the output is some constant multiple which could be positive, negative or fraction then yes it is direct variation. So just divide a couple y/x = k to see what you get.
