Finance and Population Growth

Predicting the Future with Math

Exponential and logarithmic functions are key to understanding growth in populations and investments. They help us answer: How fast will my money grow? How quickly will a population double?

Financial Applications

  • Compound interest: Money growing in a bank account.
  • Depreciation: Value decreasing over time.
  • Population models: Predicting future numbers.

Why It’s Important

These tools allow businesses and governments to plan for the future and individuals to make smart decisions about saving and investing.

Examples

  • Calculating how much a $1000 investment will be worth in 10 years.

  • Estimating when a city will reach one million residents.
