What is the percent slope of a lot that is 250 feet deep and drops 20 feet in elevation?

To find the percent slope of a lot, you can use the formula for percent slope, which is calculated as the rise (change in elevation) divided by the run (horizontal distance) multiplied by 100. In this case, the "rise" is the change in elevation, which is 20 feet, and the "run" is the depth of the lot, which is 250 feet.

Using the formula:

Percent Slope = (Rise / Run) × 100

Percent Slope = (20 feet / 250 feet) × 100

Percent Slope = 0.08 × 100

Percent Slope = 8%

Hence, the percent slope of the lot is 8%. This value aligns with option C, making it the correct answer.
