The bar graph shows changes in the percentage of college
Chapter 5, Problem 126(choose chapter or problem)
The bar graph shows changes in the percentage of college graduates for Americans ages 25 and older from 1990 to 2010. Exercises 125-126 involve developing arithmetic sequences that model the data.
In 1990, 24.4% of American men ages 25 and older had graduated from college. On average, this percentage has increased by approximately 0.3 each year.
a. Write a formula for the nth term of the arithmetic sequence that models the percentage of American men ages 25 and older who had graduated from college n years after 1989.
b. Use the model from part (a) to project the percentage of American men ages 25 and older who will be college graduates by 2019.
