![Suppose that a price \( p \) and demand \( x \) are related through the price-demand equation
\[ x + 400p = 8,000. \]
Which of the following gives the formula for the elasticity of demand at price \( p \)?
Select the correct answer below:
- \( E(p) = \frac{20 - p}{p} \)
- \( E(p) = \frac{p}{1 + p} \)
- \( E(p) = \frac{p}{20 - p} \)
