A country plans to increase its national park area by 15% each year. If the current area is 200 square kilometers, what will be the area after 1 year? (2023)
Step 1: Identify the current area of the national park, which is 200 square kilometers.
Step 2: Determine the percentage increase, which is 15%.
Step 3: Convert the percentage increase to a decimal by dividing by 100. So, 15% becomes 0.15.
Step 4: Calculate the increase in area by multiplying the current area (200) by the decimal (0.15). This gives you 200 * 0.15 = 30 square kilometers.
Step 5: Add the increase in area (30 square kilometers) to the current area (200 square kilometers). So, 200 + 30 = 230 square kilometers.
Step 6: The area of the national park after 1 year will be 230 square kilometers.
