Answer:
d) 625 grey wolves
Explanation:
Number of grey wolves in yellowstone;
1997 = 100 wolves
2002 = 275 wolves
Between 1997 and 2002 (a five year period), number of wolves increased by; 275 - 100 = 175 wolves
Population growth rate between 1997 and 2002 = 175 wolves per 5 years
Note that the population growth continued at the same rate from 2002 to 2012 (a ten year period).
Therefore;
if; 5 years = 175 wolves
10 years = (175 × 10) / 5 =350 wolves.
therefore, number of wolves between 2002 and 2012 = 350 wolves.
Number of wolves as at 2002 = 275 wolves
total number of wolves at 2012 = 350 + 275 = 625 wolves
