Well the question is written wrong but I think is 30
Answer:41.7
Step-by-step explanation:let the unknown percent be x
X\100 of 48=20
X/100 x 48 =20
48x/100= 20
Cross multiply
48x =100 x 20
48x = 2000
Divide both sides by 48
X= 2000/48
X= 41.7
59.00 x .30 = 17.70 discount from price. So the dress would be 59-17.70 and you'd get 41.30
P=2(w+l)
372=2(88+l)
372÷2=(88+l)
186-88= l
98= l
