Answer:
A=16000 B=16400
Step-by-step explanation:
1. You multiply 20,000 by .2 or 20%, because you are trying to find a part of the 20,000.
2. You get 4,000 dollars, that is 20% of 20,000. To find the sale price, you take the 20% away from 20,000, which would be 16,000 dollars. That would be your answer for the first part.
3. the sales tax is 2.5% of the sale price. Again, you multiply 16,000 dollars, your sales price, by .025 or 2.5%.
4. you would get 400 dollars. You add the 2.5% or 400 dollars because you have to pay the tax as well as the price. You would get 16,400 dollars.

The simplification of the polynomial expression will give 3x² - 20x + 8.
<h3>How to illustrate the polynomial?</h3>
The polynomial expression is given as:
(5x² + 13x4) (17x² + 7x - 19) + (5x-7)(3x + 1)
= 5x² + 13x - 4 - 17x² - 7x + 19 + 15x² + 5x - 21x - 7
Then collect like terms
= 5x² + 15x² - 17x² + (13x - 7x + 5x - 21x) - 4 - 7 + 19
= 3x² - 20x + 8.
