Answer:
1
Step-by-step explanation:
<em><u>Use the clues given.</u></em>
We know that 5% is equal to 5/100 or .05. Using one of those numbers, we can find what the answer is.
<u><em>Multiply by 20.</em></u>
In this case, I will be using .05, just because it is the easiest. So, if we multiply .05 by 20, we will get 1.
Hope this helped,
