in a forest 160 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 ?
"the percentage of tagged deer in the second sample = 5 / 50 * 100 = 10 % . so , 160 tagged deers comprise 10 % of total # of deers - - > total # of deers = 160 * 10 = 1,600 . answer : d ."
multiply(50, 5)
