109 seals

Explanation:

Let

x -----> approximate total seals in the area

we know that

In a survey, you count 58 seals, 16 of which were marked

Using proportion

Find out how many seals are in the area , if there are 30 marked seals

`(58)/(16) =(x)/(30)\\\\x=58(30)/16\\\\x=108.75\ seals`

Round to the nearest whole number

`108.75\ seals=109\ seals`
