prisoha [69]

Answer:

5280people

Step-by-step explanation:

Given parameters:

Percentage increase of population = 25%

Population now = 6600

Unknown:

Population last year = ?

Solution:

Let the population last year = y;

Then;

Percentage of last years population plus the population of last year should give us this year's population;

( $\frac{25}{100}$ of y) + y = 6600

0.25y + y = 6600

1.25y = 6600

y = $\frac{6600}{1.25}$ = 5280people

Last year, there was 5280people in the locality.
