Answer

To find Thomas's salary at the end of 1999, we need to calculate how much his salary increased over the years from his starting salary in 1977.

### Step-by-Step Solution:

1. **Identify the Starting Salary**:
Thomas's starting salary in 1977 was $40,000.

2. **Determine the Annual Raise**:
Each year, Thomas received an annual raise of $2,300.

3. **Calculate the Number of Years Worked**:
Thomas worked from 1977 to the end of 1999.
- The total number of years worked = 1999 - 1977 + 1 = 23 years.
(He worked the entire year of 1999, so we add 1.)

4. **Calculate the Total Increase in Salary**:
Since he received a raise of $2,300 each year for 22 years (from 1978 to 1999), we calculate the total increase:
- Total increase = Annual raise × Number of years of raises = $2,300 × 22 = $50,600.

5. **Calculate the Final Salary**:
Now, we add the total increase to the starting salary to find the final salary:
- Final Salary = Starting Salary + Total Increase = $40,000 + $50,600 = $90,600.

### Final Answer:
Thomas's salary at the end of 1999 was **$90,600**.
