Yes that’s the correct answer
Ignore the decimal places and do 789x38 and you get 29982. Now all you have to do is put the decimal places back. Since 789 was 7.89 it had 2 decimal places and 38 had 1 you have to move 29982 three decimal places to the left making your final answer 29.982.
The answer is 480. Because you times 200 by 6, you also times the number of male elephants with tusks (80) by 6. That means the answer is 480.
