The population in a certain town is increasing linearly each year. The population at time t=4 is 1580 and at time t=7 is 2000, where t is the number of years after 1990. If P(t) is the population at time t, which of these equations correctly represents this situation?
Select the correct answer below:

P(t)=155t+915

P(t)=150t+950

P(t)=155t+960

P(t)=140t+1010

P(t)=150t+980
