10 ft to 7 ft. Describe the percent of change as an increase or decrease.
1 answer:
percent change = (new number - old number)/(old number) * 100
percent change = (7 - 10)/(10) * 100
percent change = -3/10 * 100
percent change = -30%
A negative percent change is a decrease.
A positive percent change is an increase.
This change is a -30% change, or it can be described as a 30% decrease.
