The crucial distinction in this problem is the difference between "percent of" and "percent greater than." When a question asks for "200% percent greater than" you must remember that you add 200% of the original value to the original value. "Greater than" means "add."
So here you can apply the "200% greater than" concept by saying that the the original bonus plus 200% of that original bonus equals the new bonus. In other words, the new bonus is actually triple the original bonus. To establish the range, then start with the smallest possible bonus:
3(160) = 480. So the smallest possible bonus is $480, meaning you can eliminate A, B, and C.
Then establish the upper limit by calculating the amount 200% greater than the high-end bonus of $200:
3(200) = 600. So the largest possible bonus is $600, meaning that the only possible answer is D.
