Question
**Mathematics Problem: Calculate the Pre-Tax Nightly Cost**

Including a 9% sales tax, an inn charges $207.10 per night. Find the inn’s nightly cost before tax is added.

*Given Data and Solution Explanation:*
1. To find the base cost (cost before tax), let \( x \) be the base cost.
2. The total cost including tax is calculated by adding the tax directly to the base cost.
3. The tax rate given is 9%, so mathematically this would be:
   \[ \text{Total Cost} = x + (0.09 \times x) \]
   This simplifies to:
   \[ \text{Total Cost} = x (1 + 0.09) \]
   \[ 207.10 = x (1.09) \]
4. To solve for \( x \):
   \[ x = \frac{207.10}{1.09} \]
   \[ x \approx 190 \]
   
Therefore, the inn's nightly cost before the tax is approximately **$190.00**.

**Note:** The calculation shows how to reverse the tax added on a price to determine the original cost of the service or product before tax.
