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!

The product of the binomials (4a – 1) and (2b + 3) is 8ab + 12a - 2b - 3 the answer is 8ab + 12a - 2b - 3.
What is polynomial?
Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.
We have given two binomials (4a – 1) and (2b + 3)
The product of the two binomials is:
= (4a – 1)×(2b + 3)
After applying the distributive property:
= 4a×2b + 4a×3 -1×2b - 1×3
= 8ab + 12a - 2b - 3
As we know, the expression is the combination of constants and variables with mathematical operators.
The product of the two binomials is 8ab + 12a - 2b - 3 which is a expression having four terms.
Thus, the product of the binomials (4a – 1) and (2b + 3) is 8ab + 12a - 2b - 3 the answer is 8ab + 12a - 2b - 3.

d = 3, the common difference
a(n) = a₁ + d(n-1)
a₇ = -8 + 3(7-1)
a₇ = -8 + 3(6)
a₇ = -8 + 18
a₇ = 10
To check:
a₁ = -8
a₂ = -8 + 3 = -5
a₃ = -5 + 3 = -2
a₄ = -2 + 3 = 1
a₅ = 1 + 3 = 4
a₆ = 4 + 3 = 7
a₇ = 7 + 3 = 10
