In 1990, the percent of people over 25 years old who had a bachelor's degree or higher was 20.8%. By 2000, the percent of people over 25 with a bachelor's degree or higher was 25.6%. Assume the rate of increase is constant.

a) Write an equation that relates the percent P of people over 25 with a bachelor's degree or higher at any time t, where t is the year.
b) If the trend continues, estimate the percentage of people over 25 who will have a bachelor's degree or higher by 2004. @dumbcow
