In a forest 170 deer were caught, tagged with electronic markers, then released. A week later, 50 deer were captured in the same forest. Of these 50 deer, it was found that 5 had been tagged with the electronic markers. If the percentage of tagged deer in the second sample approximates the percentage of tagged deer in the forest, and if no deer had either left or entered the forest over the preceding week, what is the approximate number of deer in the forest?
Choose the most appropriate option:
A) 150
B) 750
C) 1,250
D) 1,700
E) 2,500
The percentage of tagged deer in the second sample = 5/50*100=

<output>10</output>
10%.   So, 170 tagged deers comprise 10% of total # of deers --&gt; total # of deers= 170*10 = 1,700.   Answer: 1,700.
