Answer:

Total number of deer in the area =
1396

Explanation:

Total sample size
=638

Number of marked deer
=48

Find out
\% of marked deer


\% marked\ deer\ =(marked\ deer )/(sample\ size)*100\\\\=(48)/(638)*100\\\\=7.52\%

Total
7.52\% of total number of deer are marked

let total number of deer in the area
=x

marked deer
=105


=7.52\% \ of\ x=105\\\\(7.52)/(100)* x=105\\\\=x=(105* 100)/(752)=1395.625\approx1396
