Question

Last year, the town of Springton received 36 inches of rain. The next year, Springton received 45 inches of rain. What was the percent of increase in rain?

Answer 1

36 inches is your 100%, so you take 45-36 which equals 9. Then that nine is your increase. So you take your increase and divide it by your 100% so 9/36 to get .25 which is 25% increase.
