Answer 1

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.
