In 1965, global concentration of carbon dioxide was 320.04ppm. In 2017, it was 406.55ppm. Calculate the percent increase of global concentration of Carbon Dioxide between 1965 and 2017. Provide an answer to the nearest whole number.
Question
In 1965, global concentration of carbon dioxide was 320.04ppm. In 2017, it was 406.55ppm. Calculate the percent increase of global concentration of Carbon Dioxide between 1965 and 2017. Provide an answer to the nearest whole number.
Solution
To calculate the percent increase of global concentration of Carbon Dioxide between 1965 and 2017, follow these steps:
-
First, find the difference in the concentration between the two years. Subtract the initial amount (1965) from the final amount (2017).
Difference = 406.55ppm - 320.04ppm = 86.51ppm
-
Next, divide the difference by the initial amount (1965) and multiply by 100 to get the percentage increase.
Percentage Increase = (Difference / Initial amount) * 100 Percentage Increase = (86.51ppm / 320.04ppm) * 100 = 27.03%
-
Round the percentage to the nearest whole number.
So, the percent increase of global concentration of Carbon Dioxide between 1965 and 2017 is approximately 27%.
