A 3%3%
B 25%25%
C 33%33%
D 50%50%
E 75%
To find the percentage decrease, subtract the final price from the original price, divide that difference by the original price, and then multiply by 100:
(200 - 150) / 200 * 100 = 50 / 200 * 100 = 0.25 * 100 = 25%
Therefore, the percentage decrease is 25%.
The correct answer is B.
