Solve the problem.
-In 1995 the United States recovered 27% of its municipal wastes through recycling, up from 17% in 1990. Let P represent the percentage recycled and t the number of years since 1990. Find a linear function P(t) that fits this Data. Use this function to predict the percentage recycled in 2003.
A) 43%
B) 39.4%
C) 41.1%
D) 44.7%

The slope of the line is (27-17)/5 = 2% per year. The y-intercept is 17%. So the equation of the line is P(t) = 2t + 17. In 2003, t = 13, so P(13) = 2(13) + 17 = 43%.
