Answer:
The number of students enrolled at a college is 18,000 and grows 3% each year. Complete parts (a) through (e).
a) The initial amount a is 18,000.
b) The percent rate of change is 3%, so the growth factor b is 1 + 0.03 = 1.03.
c) To find the number of students enrolled after one year, you calculate 18,000 · 1.03.
d) Complete the equation y = 18000 · 1.03^2 to find the number of students enrolled after x years.
e) Use your equation to predict the number of students enrolled after 21 years.
