Question:

Use the model = 343.5 + 1.55(x - 1984) that was found in the example in Lesson 3.3. Recall that x represents the year, and y represents the concentration of CO2 in parts per million (ppm) at Mauna Loa.
a. Predict the concentration of CO2 in the year 1984.
b. Use the model to predict the concentration of CO2 in the year 2010.
c. According to this model, when will the level of CO2 be double the preindustrial level of 280 ppm?
