Final answer:
To find the percent change in the number of leprechauns from last year to this year, subtract the number of leprechauns last year from the number of leprechauns this year. Then, divide the difference by the number of leprechauns last year and multiply by 100 to find the percentage change.
Step-by-step explanation:
To find the percent change in the number of leprechauns from last year to this year, we need to calculate the percentage increase or decrease in their population.
First, we subtract the number of leprechauns last year (175) from the number of leprechauns this year (230). This gives us a difference of 55.
Next, we divide the difference (55) by the number of leprechauns last year (175) and multiply by 100 to find the percentage change:
Percentage change = (Difference / Initial value) * 100 = (55 / 175) * 100 = 31.43%.
Therefore, the percent change in the number of leprechauns is approximately 31.43%.
