Greg bought a 300 gram container of sunflower seeds. He found that 15 seeds weighed about 1 gram. Approximately how many sunflower seeds are in the container?
(A) 600
(B) 4500
(C) 60000
(D) 45000
(E) 6000
Since 1 gram is the approximate weight of 15 seeds, 300 grams is the approximate weight of $300 \times 15=4500$ seeds.

Therefore, there are approximately 4500 seeds in the container.
