Answer 1

Answer:

The population of town was 53,436.1

Step-by-step explanation:

$73,960 \ (1-\dfrac{15}{100})^2\\\\\longmapsto 73960 \ (\dfrac{85}{100})^2\\\\\longmapsto 73960 \ (\dfrac{85}{100} \times \dfrac{85}{100})\\\\\longmapsto 73960 \times 0.7225\\\\\longmapsto 53,436.1$

Hence, the population was 53,436.1.
