Answer:
B. <em>x + 0.2x</em>
Step-by-step explanation:
0.2 is equal to 20%
x represents the amount of dollars, and 20% of <em>x </em>would be written as 0.2x.
The 20% of x would be added to the money before the 20%, so, the answer is b, <em>x + 0.2x</em>.

*If it helps, think of x and y as different types of candy... ;3
For example, you can't combine 12 Skittles (x) and 4 Reese's (y), because they aren't the same. So, you'd write that you have 12 Skittles and 4 Reese's.
