The population of a town is increasing by 500 inhabitants each year. If its population at the beginning of 1990 was 24,390, what was its population at the beginning of 1998?

Solution

population at the beginning of 1990 = No = 24390

population at the beginning of 1998 = N = No + 500*t

N = 24390 + 500*8 = 28390
