The graph provides the percent changes in annual city tax revenue for five cities from 1990 to 1995 and from 1995 to 2000. We are asked to calculate the tax revenue for City B in 2000, given that the tax revenue in 1990 was $800,000.

Let's break down the changes for City B:
1. **1990 to 1995**: City B experienced a **-10%** change in tax revenue.
2. **1995 to 2000**: City B had a **15%** increase in tax revenue.

### Step-by-Step Calculation:
1. **1990 to 1995**:
   \[
   \text{Revenue in 1995} = 800,000 \times \left(1 - \frac{10}{100}\right) = 800,000 \times 0.90 = 720,000
   \]

2. **1995 to 2000**:
   \[
   \text{Revenue in 2000} = 720,000 \times \left(1 + \frac{15}{100}\right) = 720,000 \times 1.15 = 828,000
   \]

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