Question
### Demand for Ceiling Fans: An Exponential Model

The demand for ceiling fans is modeled by the following equation:

\[ D(p) = 25.62(0.996^p) \text{ thousand ceiling fans} \]

where \( p \) represents the price (in dollars) of a ceiling fan.

#### (a) Price Threshold for Ceasing Purchases
**Question:** According to the model, is there a price above which consumers will no longer purchase fans? Explain why or why not.

**Model Explanation:**
The model is exponential and \( \lim_{p \to \infty} D(p) = 0 \). Therefore, there **is not** a specific price above which consumers will not purchase a ceiling fan. Consumers will always purchase fans, just in decreasing quantities as the price increases indefinitely.

#### (b) Willingness to Spend
**Question:** Calculate the amount that consumers are willing and able to spend to purchase 17 thousand ceiling fans. (Round your answer to three decimal places.)

**Solution:**
\[ \text{\$} \_ \_ \_.\_ \_ \_ \text{ thousand} \]

#### (c) Purchase Quantity at Specific Market Price
**Question:** How many fans will consumers purchase when the market price is $100? (Round your answer to three decimal places.)

**Solution:**
\[ \text{\_ \_ \_.\_ \_ \_ \text{ thousand fans}} \]

#### (d) Consumers' Surplus
**Question:** Find the consumers' surplus when the market price is $100. (Round your answer to three decimal places.)

**Solution:**
\[ \text{\$} \_ \_ \_.\_ \_ \_ \text{ thousand} \]

This model provides a framework for understanding consumer behavior and how demand changes with pricing. Further exercises can help in applying this model to real-world scenarios and enhancing conceptual understanding.
