**Elasticity Calculation for Demand Analysis**

The elasticity of demand, $ E_A $, is expressed by the formula:

\[
E_A = \frac{\partial Q_S}{\partial W} \cdot \frac{W}{Q_S}
\]

where:
- $ \frac{\partial Q_S}{\partial W} $ is the partial derivative of the quantity demanded with respect to income (W),
- $ W $ is the income,
- $ Q_S $ is the quantity demanded.

**Question 1(j):**
Does this elasticity coefficient indicate that the demand for Smooth Sailing boats is relatively responsive to changes in income? Explain why or why not.

*Elasticity7.docx 060272022*

**Explanation:**
In this context, elasticity measures how sensitive the quantity demanded of Smooth Sailing boats is to changes in consumer income. If the elasticity coefficient is greater than 1, the demand is considered elastic, meaning that demand is highly responsive to income changes. If it is less than 1, demand is inelastic, indicating less sensitivity to income changes.
