The bar graph indicates that fewer U.S. adults are getting married.
The data can be modeled by the following system of linear equations:
Percentage of never-married American adults, y, x years after 1970
Percentage of married American adults, y, x years after 1970
a. Use these models to determine the year, rounded to the nearest year, when the percentage of never-married adults will be the same as the percentage of married adults. For that year, approximately what percentage of Americans, rounded to the nearest percent, will belong to each group?
b. How is your approximate solution from part (a) shown by the following graphs?
