The tables below give Social Security Administration data for the U.S. average annual wage from 2011 and projected to 2021 and for selected years from 2012 and projected to 2050.

(a) Make a scatter plot of each of these data sets with x as the number of years past 2010.

(b) Decide which one function type could be used as a model for both data sets and find the two models. Let a(x) be the model for the data to 2021 and A(x) be the one for data to 2050. Report both models with 4 significant digit coefficients.

(c) How well do the reported models agree for the data points for 2020 and for 2050?

(d) When does each reported model predict the average annual wage will reach $150,000?
