Answer:$50
Step-by-step explanation:
So we have the sweater that’s $30 with a sale of 60% of the original price.
That means $30=60% of the original
So
30=60%start with this 
5=10% divide 6 by both sides to get 10%
50=100% times by 10 to get 100%, which is the original price. 
So the original price of this sweater is $50 
:D

Answer:
x = 7.5
Step-by-step explanation:
Since DF bisects ∠CDE then
∠EDF = ∠CDF, hence
8x = 4x + 30 ( subtract 4x from both sides )
4x = 30 ( divide both sides by 4 )
x = 7.5
