The expression that represents the town's population after 5 years.
Current population of Springfield, USA = 9,900
Rate of growth per year = 2.3%
To find the expression that represents the town's population after 5 years.
The exponential growth expression is given as:
represents the final population after years
represents the initial population
represents the rate of growth in percent
Plugging in the known values.
Thus, the above expression represents the population after 5 years.
This is an example of an exponential equation. They are in the form y = ab^x. A is the starting value and b is the rate of change.
The rate is 1.023 because we are adding on 2.3% each time.
