Laketown had 215 inches of snowfall last year, but only 155 inches this year. what was the percent decrease in snowfall for laketown to the nearest percent?

Quantity of snowfall in Laketown last year = 215 inches
Quantity of snowfall in Laketown this year = 155 inches
Then
Amount of decrease of snowfall in Laketown this year = (215 - 155) inches
                                                                                       = 60 inches
So
Percentage of decrease of snowfall in Laketown this year = (60/215) * 100
                                                                                             = 6000/215 percent
                                                                                             = 27.906 percent
                                                                                             = 27.91 percent
So the percent decrease in snowfall for Laketown to the nearest percent is 27.91%. I hope the procedure for doing this problem is clear enough for you to understand.
