Say $8.00 is 5% of the number I'm looking for. What does the equation look like?

Multiply by 20. The first person who answered your question is a knucklehead. Multiply by 1.05? What's she been smoking? The second person who answered your question hit the nail right on the head. You don't need to read any more answers. You shouldn't even be reading my answer. Thanks for the points, anyway.
Multiply by 20 is correct.

5% is the same as saying 5 out of 100
so if $8.00 is the same proportion as 5 of 100
5/100 = 8/x
solve for x to get 160

5% is 5/100. Reduce to 1/20.
$8.00 is therefore 1/20th the total number
Multiply $8.00 by 20 to get $160.00.
You can check it by multiplying $160.00 by 5% and you'll get $8.00
Mathematically:
8/x=5/100
8/x=1/20(cross multiply)
8*20= 1*x
160=x

8 = 1/20X Note that 0.05 = 1/20
(20)8 = X
160 = X
Answer is $160. Check: 160 X 0.05 = 8.00 dollars

If you know $8 is 5% of your total (T), then you know:
8 = (5 / 100) * T
mutliply through by 100:
8 * 100 = 5 * T so 800 = 5T
divide through by 5:
800 / 5 = T
So your total amount is 160. $8 is 5% of $160

8$ is 5% of a number
X is 100%
100*8/5 = x
x=$160.

if 8 is 5% then when you divide 100 by 5 it's 20 so 20 times 8 is 100%!!

is over of
5% $8.00
100 X
5/100 = 1/20
$8 x 20 = $160
1% x X = 1x
X= 160

You do 8 over x = 5 over 100. Set it up as a proportion.
5x=800... divide by 5 on both sides.
x = $160

That first answer is wrong - ignore it!
5% can be written in decimal as 0.05. If X is the total value, then you have:
X = 8/0.05
so X = 160.
