To find the percentage decrease, we need to find the difference in the number of toys and express it as a percentage of the original number of toys.
The difference in the number of toys is 55 - 30 = 25 toys.
To express this difference as a percentage of the original number of toys, we divide 25 toys by the original number of toys (55) and multiply by 100%: (25/55) * 100% ≈ 45.45%.
Therefore, Heather decreased the amount of toys by approximately 45.45%, which is closest to option C) 45%.
