Answer: $56.97

=============================================

Explanation:

"25% off" means the buyer pays 75% of the original cost, ignoring any other taxes, fees, shipping, etc.

75% = 75/100 = 0.75

Multiply this decimal value with the original cost 72 and we get 0.75*72 = 54.

-----------

Now we compute the sales tax

5.5% = 5.5/100 = 0.055

0.055*54 = 2.97 is paid in tax

-----------

Add the sales tax ($2.97) to the discount price ($54) to get 54+2.97 = 56.97

We don't add on shipping because that is free. The sales tax is applied after the discount is done, or else it would imply that the 25% discount didn't fully go through (ie you are paying some portion of what was promised to be saved)

A shortcut is to compute: 72*0.75*1.055 = 56.97 which allows us to basically find the answer in one single step. The 1.055 refers to the 5.5% tax multiplier. A similar trick can be used if you have multiple discounts applied simultaneously.

If ABC = ADC, which is NOT true by CPCTC ?
sdas [7]
We cannot use CPCTC to show that BE is congruent to DE.

CPCTC refers to the angles and sides of two congruent triangles being congruent to their corresponding pieces.  The height of a triangle is not one of the given sides that counts in this.
