The population of a small town in central Florida has shown a linear decline in the years 1985-1995. In 1985 the population was 28900 people. In 1995 it was 22500 people. A) Write a linear equation expressing the population of the town, \( P \), in terms of \( t \), the number of years since 1985. Answer: \( P= \) B) If the town is still experiencing a linear decline, what will the population be in 1998? B
