The amount paid by Heron for the video game is $46.64.
Step-by-step explanation:
Here, the marked price of the video game = $55
The discount percentage on the video game = 20%
Calculating 20% of the $55, we get:
So, the discount offered on the video game = $11
Selling Price = Marked Price - Discount
=$55 - $11 = $44
Now, the tax percentage on the video game = 6%
Calculating 6% of the $44, we get:
So, the tax on the video game = $2.64
New Selling Price = Selling Price + Tax
=$44 + $2.64 = $46.64
So, the amount paid by Heron for the video game is $46.64.

It is quadratic equation.
First we have find delta given by formula: delta=
where our
a=16
b=-24
c=7
so, delta=
Because delta is positive, there is real results.
Now we can use next formula x=
, to find roots (results, 2 results because its quadratic equation and delta is greater than 0)
x1=
x2=
