I'm reclassified but I'm still a 10th grader and the only class I need to take is Algebra1B So here's the problem. I'm 1990, the town of Belgrade, Montana, had a popuof of 3422. For each of the next 8 years, the population increased by 4.9% per year.
a. Write an equation for the population of Belgrade in 1998
b. Find the population of Belgrade in 1998.

if t is the number of years since 1990, then the population

p(t) = 3422 * 1.049^t

now just plug in any value for t that you need. Just recall that the function is only valid for 0<=t<=8
