The graph shows the percent changes in annual city tax revenue for five cities from 1990 to 1995 and from 1995 to 2000. Specifically, for **City B**, we see:

- A decrease of approximately **10%** from 1990 to 1995.
- An increase of approximately **15%** from 1995 to 2000.

We are given that the tax revenue in **City B** was $800,000 in 1990, and we need to find the tax revenue in City B by the year 2000.

### Step-by-step solution:

1. **1990 to 1995:**
   The tax revenue decreases by 10% between 1990 and 1995. 
   
   \[
   \text{Tax revenue in 1995} = 800,000 - (0.10 \times 800,000) = 800,000 - 80,000 = 720,000
   \]

2. **1995 to 2000:**
   The tax revenue increases by 15% between 1995 and 2000. 
   
   \[
   \text{Tax revenue in 2000} = 720,000 + (0.15 \times 720,000) = 720,000 + 108,000 = 828,000
   \]

Thus, the annual tax revenue in **City B in 2000** was **$828,000**.

Here are some related questions to expand your understanding:
1. How would the tax revenue change if the percentage increase from 1995 to 2000 was 20% instead of 15%?
2. What would the revenue be in 2000 if City B's initial revenue was $1,000,000 in 1990 instead of $800,000?
3. How would the result change if there was a 5% increase from 1990 to 1995 instead of a 10% decrease?
4. Can you explain how to calculate the final tax revenue if both changes were negative?
5. How does the percent change affect the final revenue, and what trends can be observed across all cities?

**Tip:** Always break down percent change calculations into stepwise parts, starting with the base amount.
