It is observed that Earth's average surface temperature has increased from 56.58°F in 1900 to 58.09°F in 2013. Many experts believe that this increase in global temperature is largely due to the increase in the amount of carbon dioxide in the atmosphere. The pre-industrial concentration of atmospheric carbon dioxide was 289
parts per million (ppm). The following table shows the atmospheric concentration of carbon dioxide in parts per million, measured in a city. Complete parts a through e
1954 2006
C, Carbon Dioxide Concentration (ppm) 316
a. Lett represent the number of years since 1954. Determine the average rate of increase in the atmospheric concentration c of carbon dioxide from 1954 to 2006.
Interpret the rate in the context of this situation.
(Type an integer or decimal rounded to the nearest hundredth as needed.)
A. The average rate of increase is it can be interpreted as an average gain for each year.
B. The average rate of increase is It can be interpreted as an average gain for year 2006.
OC. The average rate of increase is It can be interpreted as an average gain for year 1954.
