Initial values are:      PX = $9500     PY = $10000   I = $15000      A = $170000   W = 160

This function is:        Qs = 89830 -40PS +20PX +15PY +2I +.001A +10W

**Elasticity and Demand Analysis for Smooth Sailing Boats**

1. **Advertising Expenditures and Demand Responsiveness**
   - **Question (a):** Does this elasticity coefficient indicate that the demand for Smooth Sailing boats is relatively responsive to changes in advertising expenditures? Explain why or why not.

2. **Weather Conditions and Point Elasticity**
   - **Question (b):** Weather forecasters emphasize the importance of favorable weather days as a determinant of sailboat sales. Calculate the point elasticity of demand for Smooth Sailing boats, assuming \( P_s = \$9000 \) (thus \( Q_s = 101600 \) boats) and \( W = 160 \). The other variables and their values are provided at the top before question #1. The formula for calculating elasticity is:
   \[
   E_A = \frac{\partial Q_s}{\partial W} \cdot \frac{W}{Q_s}
   \]

3. **Income Changes and Demand Sensitivity**
   - **Question (c):** Does this elasticity coefficient indicate that the demand for Smooth Sailing boats is relatively responsive to changes in income? Explain why or why not.
