Over the past ten years, the town's population doubled in size. The population is currently 12,000. Use the variable, P, to represent the town’s original population. Set up an equation and find the original population of the town ten years ago.
Answer provided by our tutors
P = original population
A = 12,000 current population
t = 10 years the time in years
The equation that describes the population after t years is:
A = P*(2^t)
We plug the given values into the above equation:
12,000 = P*(2^10)
P*(2^10) = 12,000
