Answer: A, or 0.2x
Step-by-step explanation:
To figure how expressions and percent's match up, replace the x with an easy number. For example, I use 4.
20% of 4 is 0.8, and 4 x 0.2 is also 0.8
Therefore, the expression to represent that percentage is A.
Also, the other answers were WAYYY off.
B, or x - 20 is flawed since x could be anything.
C, is also flawed in the same way.
And D makes -76.
A is the only sensible one and is proven to work.
Hope this helped!
