You mark it up 20% Price + 20% = p + 20/100p = p (1 + 0.20 ) = 1.2 p
6.45 * 1.2 = 7.74
You take off 5% which by the same reasoning (almost) means p/1.05
7.74 / 1.05 = 7.37
Now you need a sales tax
7.37 * 1.06 = 7.81 dollars.
Answer: The customer paid 7.81 <<<<=====

Polynomial with a degree of 3 (due to 3 intersection points). Since the end of the graph is approaching positive infinity, we also know the equation of this graph has a positive coefficient.
(I don't know if you're in calculus yet, but...) We also know that there is a local min and local max, as well as inflection points as the graph changes concavity.
