Answer 1

Hi Asia.  Hope this is helpful.

 

Here is what we know:

The total paid is $120

The cost of the shoe is the total minus the tax.

Or you could say the cost of the shoe plus taxes on the shoe cost = $120

We know how much the taxes are.

They are 6.75% or 0.0675 (times cost of item)

 

Let's set this up as an equation.

Shoe Cost + (Shoe Cost times tax rate) = total cost

Let's make x = Shoe Cost

 

Let's clean up our formula and formalize it:

x + 0.0675x = 120

1.0675x = 120   {here we combined the x's}

x = 120/1.0675  {divide both sides by 1.0675 to isolate x}

x = $112.41

 

The shoe's retail price is $112.41.

 

Can you do the second part?
Its very similar...but you are dealing with a discount rather than a tax charge.
