Answer:
30 Owls.
Explanation:
60 owls / 4 years = 15 owls per year. Since we want to know the increase in owls for the next 2 years, we can multiply the average increase per year (15 owls) by the number of years (2). 15 owls per year is 2 years = 30 owls. The population of owls in the region is expected to grow by 30 owls in the next 2 years if the current rate of increase continues.
