an increase of 27.9%
an increase of 38.7%

Answer 1

To find the percent decrease in county-designated open space from 2000 to 2020, the initial and final acreages are compared, revealing a 27.9% decrease following the formula for percentage change.

Step-by-step explanation:

The question is asking to calculate the percent decrease in county-designated open space from 2000 to 2020. First, find the difference in acreage between the two years, then divide that number by the acreage in the initial year (2000) to find the decrease as a fraction.

Finally, multiply by 100 to get the percentage.

Decrease in acreage = Initial acreage - Final acreage

Decrease in acreage = 215.75 acres - 155.6 acres

Decrease in acreage = 60.15 acres

Percentage decrease = (Decrease in acreage / Initial acreage) × 100

Percentage decrease = (60.15 acres / 215.75 acres) × 100

Percentage decrease ≈ 27.9%

Therefore, the answer is a decrease of 27.9% in the amount of open space from 2000 to 2020.
