Transcript text: The demand for a product is given by $x=F(p)=\frac{1840}{5+\ln (2+p)}$.
If $p=30$, determine $E$ and interpret the results.
Solution
Solution Steps
To solve this problem, we need to calculate the elasticity of demand E at a given price p=30. The elasticity of demand is given by the formula E=xp⋅dpdx. First, we need to find x by substituting p=30 into the demand function. Then, we calculate the derivative dpdx of the demand function. Finally, we substitute these values into the elasticity formula to find E.
Step 1: Calculate Demand at p=30
We start by substituting p=30 into the demand function x=5+ln(2+p)1840:
