Answer: 340
Step-by-step explanation:
Given: There are 15 plant-eating mammals for every 2 meat-eating mammals.
i.e. ratio of meat-eating mammals to plant eating animals = 2:15 or [tex]\dfrac2{15}[/tex]
ratio of meat-eating mammals to total population = [tex]\dfrac{2}{17}[/tex]
Total population: 2,900 (approx.)
The population of meat-eating mammals in the valley = [tex]\dfrac{2}{17}\times2900[/tex]
[tex]\approx341[/tex]
From the given options, the best estimate of the population of meat-eating mammals in the valley = 340
