Question

Steve measured a pile that was 6 feet tall. The next day the snow pile was only 4.5 feet tall. What is the percent of decrease

Answer 1

`percent ~change = (new~number - old~number)/(old~number) * 100`

Here, the new number is 4.5. The old number is 6.

`percent ~change = (4.5 - 6)/(6) * 100`

`percent ~change = (-1.5)/(6) * 100`

`percent ~change = -0.25 * 100`

`percent ~change = -25`

Since the percent change is negative, it is a percent decrease.

Answer: The percent decrease is 25%.
