Answer:
102,476
Step-by-step explanation:
If a population grows linearly from 55556 in 2000 to 72760 in 2011, you want the predicted value in 2030 assuming growth continues to be linear.
Proportion
The change in population is proportional to the change in years:
(72760 -55556)/(2011 -2000) = (p -55556)/(2030 -2000)
p = 30(17204)/11 +55556 . . . . . . solve for p
p = 46920 +55556 = 102,476 . . . . . . do the arithmetic
The population in 2030 will be $102,476.
