<h2>Answer:</h2><h2>The population of the city after 7 years = 569,859</h2>

Step-by-step explanation:

The population of the city of Miami = 463,300

The rate of increase in population every year = 3%

The population of the city after 7 years = ?

By formula, $P_{n} = P (1 +\frac{r}{100})^{n }$

Pn is the population after 7 years

P is the current population = 463,300

r = 3 %, n = 7

$P_{7} = 463300 (1 +\frac{3}{100})^{7 }$

= 463300 (1.23)

= 569859

The population of the city after 7 years = 569,859
