Answer 1

Answer:

6000

Step-by-step explanation:

population= 10000

rate at which population decreases per year= 20%

% of population decreased after 2 years= (20% + 20%)=40%

population decreased after 2 years= 10000- 40% of 10000

                                                     =10000- 4000

                                                     = 6000
