First the original price is reduced by 15%
assume the original price is x
100%-15%=85%..u r left with 85% of the price
thus,85/100 multiply x
the reduced price is reduced again by 5%
so,95/100 ×(85/100 x)=$315.32
find x
323/400 x =$315.32
×=$390.49

Answer:
x = ± 
Step-by-step explanation:
9x² - 4 = 0 ( add 4 to both sides )

x² =
( take the square root of both sides )
x = ±
= ±
= ± 
if you had two,two digit number it can no result in a 4 digit number
