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!

Price of boots is represented as x, price of tennis shoes is represented as y.
x-y=44.38
x+y=196.12
Isolate x. (Or y, if you wanted to)
x=y+44.38
x=196.12-y
Set them equal to each other.
y+44.38=196.12-y
Solve for y. Then plug it in to either of the two original equations to find x.
x=120.24
y=75.86
Note: This is assuming that the boots are more expensive than the tennis shoes. If the tennis shoes are more expensive than the boots, then the prices would be switched. I didn't find this clear in your question.

Answer:
6
Step-by-step explanation:
For a quick rough estimate, I'd round 9.1% up to 10% and 59.3 to 60. 10% of 60 is 0.1(60) = 6.
For a more accurate estimate, round 9.1% down to 9% and 59.3 up to 60. Then 9% of 60 is 5.4.
