The number of students at a university is 1320, and the number oncrease by 8% each year . then find about how many students there will be in 5 years

This is exponential growth of the form:

final=initial(r^t)  in this case:

s(t)=1320(1.08^t)

s(5)=1320(1.08^5)

s(5)=1939.513061376  Since the amount of people must be an integer...

s(5)=1939 students
