Answer:
$24.375
Step-by-step explanation:
Regular price of sandals = $32.50
Store sells sandals for 25% of the regular price.
Hence selling price =(100-25)% of the regular price.
In other words, selling price = 75% of regular price
= 75% of $32.50
= ![\[\frac{75}{100}*32.50\]](https://tex.z-dn.net/?f=%5C%5B%5Cfrac%7B75%7D%7B100%7D%2A32.50%5C%5D)
= ![\[24.375\]](https://tex.z-dn.net/?f=%5C%5B24.375%5C%5D)
Hence the sale price of the sandals is $24.375
This is $8.125 less than the regular price of the sandal.
Another way to think about this is that $12590 is 80% of the original price. The original was 100%, but this price is 20% off so 100%−20%=80% . The way I like to think is that since I know 12590 is 80%, I can find how much 1% is by dividing 12590 by 80. 12590÷80=157.375.

Step-by-step explanation:
![{x}^{4} - 16 \\ = ({x}^{2})^{2} - ({2}^{2})^{2} \\ = ( {x}^{2} - {2}^{2} )( {x}^{2} + {2}^{2} ) \\ = (x - 2)(x + 2)( {x}^{2} + 4)](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B4%7D%20%20-%2016%20%5C%5C%20%20%3D%20%20%28%7Bx%7D%5E%7B2%7D%29%5E%7B2%7D%20%20%20-%20%20%28%7B2%7D%5E%7B2%7D%29%5E%7B2%7D%20%20%20%5C%5C%20%20%3D%20%28%20%7Bx%7D%5E%7B2%7D%20%20-%20%20%7B2%7D%5E%7B2%7D%20%29%28%20%7Bx%7D%5E%7B2%7D%20%20%2B%20%20%7B2%7D%5E%7B2%7D%20%29%20%5C%5C%20%20%3D%20%28x%20-%202%29%28x%20%2B%202%29%28%20%7Bx%7D%5E%7B2%7D%20%20%2B%204%29)
Because
can further be factorised as (x - 2) (x + 2).
