Answer:

C; multiply 4 to both sides

Step-by-step explanation:

When you want to solve for a variable, you always want to isolate it.

So, to move 4, we have divide:

[tex]\frac{A}{4}[/tex] = [tex]\frac{4r}{4}[/tex].

The 4 in 4r is "one'd" out, and now we have 1r, or simply r.

Now, we have r = A/4
