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
Cross multiplying
42 X x = 630 X 90
Dividing both sides by 42
The total number of squirrels in the city park is 1350.
