An interglacial is a period of time that occurs between Ice Ages. During previous interglacials, the CO2 levels in the atmosphere were about 300 parts per million (ppm). In 2013, they were approximately 420 ppm. Rounding to the nearest percent, what is the percent increase in CO2 between these two time periods?
Answer:
40% increase
Explanation:
Percentage Increase Formula:
Percentage Increase=[(Final Value−Starting Value)/|Starting Value|] ×100%
To Calculate Percentage Increase:
1) Subtract final value (later value) minus starting value (initial value)
2) Divide that amount by the absolute value of the starting value (initial value)
3) Multiply by 100 to get percent increase
Keep in mind: If the percentage is negative, it means there was a decrease and not an increase.
So for your problem,
[(420-300)/300]*100% = 40% increase
