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:
[tex]35\cdot0.5=17.5[/tex]
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 [tex]35+17.5 = 52.5[/tex]
So four pairs cost [tex]52.5\cdot2 = 105[/tex]
However, there is a tax of 6.5%
So we can multiply 105 by 1.065 to get the cost after tax.
[tex]105\cdot1.065=111.825[/tex]
This simplifies down to 111.83.
Hope this helped!
