Answer: 45.45%
Step-by-step explanation:
Given: The number of toys in Heather's room before = 55
The number of toys now in the room = 30
Now, the decrease in the toys = [tex]55-30=25[/tex]
We know that the percent decrease is given by ;-
[tex]\dfrac{\text{Decrease in amount}}{\text{amount before}}\times100[/tex]
[tex]\\=\dfrac{25}{55}\times100=45.4545\approx45.45\%[/tex]
Hence, Heather decrease the amount of toys by 45.45% .
