Answer:
(C) $111.83
Step-by-step explanation:
If Sonya buys four pairs of shoes, each on a buy one get one 50% off, that means that we can find the value if she bought ONE deal of buy one get 50% off one, then multiply that by 2 (as if you do the deal, you are paying for two.)
The shoe costs $35, and if we have a 50% discount on it:
So the cost of the shoe ON DISCOUNT is 17.50, however the first pair still stays the same.
So the cost of two pairs of shoes using the discount is
So four pairs cost
However, there is a tax of 6.5%
So we can multiply 105 by 1.065 to get the cost after tax.
This simplifies down to 111.83.
Hope this helped!

Answer:
Impossible
Step-by-step explanation:
In 5x^2-4x+3=0, standard form, substitute these values in the quadratic formula:
a = 5; b = -4; c = 3
The quadratic formula is
(ignore the weird capital A)
Substitute a b and c:
Simplify:
Because is the square root of a negative number, the answer would be imaginary.
Therefore, there are not solutions to this equation.
A solution is the same as the roots or zeroes, where the graph would cross the x-axis when graphed.
The graph never meets the x-axis. It looks like this:
