Question
A city has a population of 360.000 people. Suppose that each year the population grows by 7,25%. What will the population be after 14 years?
Solution
Para resolver este problema, utilizaremos la fórmula del crecimiento exponencial:
donde:
- es la población después de años.
- es la población inicial.
- es la tasa de crecimiento anual.
- es el número de años.
En este caso:
Sustituyendo estos valores en la fórmula:
Primero, calculamos :
Luego, elevamos este resultado a la potencia de 14:
Finalmente, multiplicamos este resultado por la población inicial:
Por lo tanto, la población después de 14 años será aproximadamente 949,000 personas.
