C = 0.5x + 10
----------------------------------------------------------
Switch side :
----------------------------------------------------------
0.5x + 10 = c
----------------------------------------------------------
Take away 10 from both sides :
----------------------------------------------------------
0.5x = c - 10
----------------------------------------------------------
Multiply by 2 through :
----------------------------------------------------------
x = 2c - 20
----------------------------------------------------------
Answer : x = 2c - 20 (Answer A)

Step-by-step explanation:
<h3>
Answer:</h3>
<h3>
Explanation:</h3>
Represent the sentence mathematically. 
Distribute. 
Add 6 on both sides. 
Divide both sides by 2.
Let W=width of parking lot,
then Length = W+3
Total area = W(W+3)=550
Exapand and express in standard quadratic form
W^2+3x-550=0
Factor
(W+25)(W-22)=0
Therefore W=22 or W=-25, reject negative root, so
Width = 22'
Length=22+3=25'
Check: (area = 22' * 25'=550 sq. ft, ok)
