A 25%25%
B 40%40%
C 45%45%
D 83%83%
E 120%
To find the percentage decrease, we need to calculate the difference between the original and final amount of toys, and then divide that by the original amount and multiply by 100.
The difference between the original and final amount of toys is 55 - 30 = 25.
The percentage decrease is (25/55) * 100 = 45%.
Therefore, the correct answer is C) 45%.
