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.
