p(t)= 20(4t+3)/2t+5

, where P(t) is the population, in thousands, and t is time, in years, since the start of 1990.

a) Is the population currently increasing or decreasing? Justify your answer.

b) The town will need its own transit system if the population exceeds

50 000. Will the town’s population ever exceed 50 000? Explain.
