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
[tex]\frac{58}{16} =\frac{x}{30}\\\\x=58(30)/16\\\\x=108.75\ seals[/tex]
Round to the nearest whole number
[tex]108.75\ seals=109\ seals[/tex]
