The concentration of carbon dioxide in the Earth's atmosphere is currently around 415 parts per million (ppm). If the concentration of carbon dioxide continues to increase at the current rate of 2 ppm per year, what will the concentration of carbon dioxide be in 50 years?
515 ppm
615 ppm
715 ppm
815 ppm
We can solve this problem by using a simple linear equation, where the concentration of carbon dioxide is the dependent variable and time is the independent variable. Let's assume that the initial concentration of is 415 ppm at time t = 0, and the rate of increase is 2 ppm per year. We can express this as:
where t is the time in years. To find the concentration of after 50 years, we can substitute t = 50 into the equation and solve for
Therefore, the answer is (1) 515 ppm.
