Question

To determine the squirrel population in a city park, researchers tagged 90 squirrels. Later, they counted 630 squirrels, 42 of which had tags. Based on this data, what is the total number of squirrels in the park?

Answer 1

Answer:

1350

Step-by-step explanation:

Initially 90 squirrels were tagged out of a total population of x squirrels.

Similarly, 42 squirrels out of a sample of 630 squirrels had tag

We can use ratio equality to find the total population x.

42:90=620:x

$\frac{42}{90} =\frac{630}{x}$

Cross multiplying

42 X x = 630 X 90

Dividing both sides by 42

$x=\frac{630 X 90}{42} \\=1350$

The total number of squirrels in the city park is 1350.
