We are given the retail price of desk as $320. The store takes 50% off of the retail price of desk, then its price would become half of the original.
So its new price would be $160.
Now it says that it takes an additional 20% off of all furniture on store's holiday sale. So we need to cut off 20% from new price $160.
Holiday discount = 20% of $160 = 0.2 × 160 = 32.
Final selling price would be = $160 - $32 = $128.
So $128 is the final answer.

![3(5x - 4) < 15x \\ 15x - 12 < 15x \\ 15x - 15x < 12 \\ 0 < 12](https://tex.z-dn.net/?f=3%285x%20-%204%29%20%3C%2015x%20%5C%5C%2015x%20-%2012%20%3C%2015x%20%5C%5C%2015x%20-%2015x%20%3C%2012%20%5C%5C%200%20%3C%2012)
Answer:
![3 \sqrt{11}](https://tex.z-dn.net/?f=3%20%5Csqrt%7B11%7D%20)
Step-by-step explanation:
Since we are given the hypotenuse which is 18 since it slanted, and leans on the house. And we are given one of the legs which is 15 since it is vertical. We can use the pythagorean theorem to solve for this problem.
![{a}^{2} + {b}^{2} = c {}^{2}](https://tex.z-dn.net/?f=%20%7Ba%7D%5E%7B2%7D%20%20%2B%20%20%7Bb%7D%5E%7B2%7D%20%20%3D%20c%20%7B%7D%5E%7B2%7D%20)
where a and b are the legs and c is the hypotenuse l.
Let plug it in
![{a}^{2} + 15 {}^{2} = {18}^{2}](https://tex.z-dn.net/?f=%20%7Ba%7D%5E%7B2%7D%20%20%2B%2015%20%7B%7D%5E%7B2%7D%20%20%3D%20%20%7B18%7D%5E%7B2%7D%20)
![{a }^{2} + 225 = 324](https://tex.z-dn.net/?f=%20%7Ba%20%7D%5E%7B2%7D%20%20%2B%20225%20%3D%20324)
![{a}^{2} = 99](https://tex.z-dn.net/?f=%20%7Ba%7D%5E%7B2%7D%20%20%3D%2099)
![a = \sqrt{99}](https://tex.z-dn.net/?f=a%20%3D%20%20%5Csqrt%7B99%7D%20)
![a = \sqrt{9 \times 11}](https://tex.z-dn.net/?f=a%20%3D%20%20%5Csqrt%7B9%20%5Ctimes%2011%7D%20)
![a = 3 \sqrt{11}](https://tex.z-dn.net/?f=a%20%3D%203%20%5Csqrt%7B11%7D%20)
