Answer 2

Answer:

6624

Step-by-step explanation:

Let the male population in 2019 is $P_{2019}$.

Given that male population declined by 8% from 2018 to 2019, and the population of males in 2018 was 7200.

$\implies P_{2019}=P_{2018}-P_{2018}\times \left(\frac{8}{100} \right)\\\implies P_{2019}=7200-7200\times8/100 = 6624$
