Question

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?

Answer 1

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.
