a. Estimate the yearly increase in the average atmospheric concentration of carbon dioxide. Express the answer in parts per million, rounded to the nearest hundredth.
b. Write a mathematical model that estimates the average atmospheric concentration of carbon dioxide, C, in parts per million, x years after 1950.
c. If the trend shown by the data continues, use your mathematical model from part (b) to project the average atmospheric concentration of carbon dioxide on 2050.
