-24a²- 6a +9 = - 3(8a² +6a - 9)
8a² +6a - 9 =0
x=(-b +/-√(b² - 4ac))/2a
x = (-6 +/-√(36+4*8*9) /(2*8) = (-6 +/-√(324) /16 = (-6 +/-18)/16
x1 = (-6 +18)/16 = 0.75
x2 = (-6 -18)/16 = - 1.5
-24a²- 6a +9 = - 3(8a² +6a - 9) = -3(a - 0.75)(a + 1.5)

I don’t know if I’m right but that’s think A
Answer:
$ 99.60
Step-by-step explanation:
Thinking process:
According to financial data, the inflation rate in 1995 was at 2.5 %.
In 2016, the inflation rate was at 2.1 %
The difference was: 2.1 - 2.5 = -0.4 %
The price in 2016 = Original price - Adjusted price
Adjusted price = 
The new price will be 
The new price will be $ 99.60
