Answer:
1914
Step-by-step explanation:
Let the estimated total population of the deer =x
Out of x, 638 were tagged.
Out of 105, 35 were marked.
Expressing this as a ratio of the total to tagged, we have:
x:638=105:35
[tex]\dfrac{x}{638}=\dfrac{105}{35} \\$Cross Multiply\\35x=105*638\\x=(105*638)\div 35\\x=1914[/tex]
Therefore, the total deer population in the area is approximately 1,914.
