Identify the percent of change (POC) as an increase or decrease. Then find the percent of change. Round to the nearest tenth of a percent if necessary.



-12 inches to 36 inches

-50 punds to 35 pounds

-10 gallons to 24 gallons

-16 centimeters to 44.2 centimeters


If you could explain this as simple as possible with the work, for I have problems understanding things well, then that would be a HUGE help!


If you can answer all 4, I'm awarding 20 points!!

percent change=(change/original) tiimes 100
change= |original-new|

so
12 to 36
|12-36|=|-24|=24
so
pcercent change=100 times (24/12)=100 times 2=200%

50 to 35
|50-35|=|15|=15
percent change=100 times (15/50)=100 times 100 times 0.30=30%

10 to 24
|10-24|=|-14|=14
percent change=100 times (14/10)=100 times 1.4=140%

16 to 44.2
|16-44.2|=|-28.2|=28.2
percent change=100 times (28.2/16)= 100 times 1.7625=176.25%

answers are

-12 inches to 36 inches: 200%
-50 punds to 35 pounds: 30%
-10 gallons to 24 gallons: 140%
-16 centimeters to 44.2 centimeters: 176.25%
