is this correct?

Yes, 28%

To calculate the percent decrease in snowfall for Laketown, you need to find the percentage decrease from the previous year's snowfall to this year's snowfall.

First, subtract the snowfall for this year (155 inches) from the snowfall for last year (215 inches) to find the decrease in snowfall:

215 - 155 = 60 inches

Next, divide the decrease in snowfall by the snowfall from last year and multiply by 100 to find the percentage decrease:

(60 / 215) * 100 ≈ 27.91%

Since the question asks for the answer to the nearest percent, the percent decrease in snowfall for Laketown is approximately 28%.

Therefore, the correct answer is A. 28%.
