Answer:
135
Step-by-step explanation:
The given expression is
![\frac{2 {x}^{2} }{x} +x(100 - 15x)](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%20%7Bx%7D%5E%7B2%7D%20%7D%7Bx%7D%20%2Bx%28100%20-%2015x%29)
From the question, x=5
So,by substitution,we obtain
![=\frac{2({5}^{2})}{5} +5(100 - 15(5))](https://tex.z-dn.net/?f=%20%3D%5Cfrac%7B2%28%7B5%7D%5E%7B2%7D%29%7D%7B5%7D%20%2B5%28100%20-%2015%285%29%29)
![=\frac{2(25)}{5} +5(100 - 75))](https://tex.z-dn.net/?f=%20%20%3D%5Cfrac%7B2%2825%29%7D%7B5%7D%20%2B5%28100%20-%2075%29%29)
![=2(5)+5(25)](https://tex.z-dn.net/?f=%20%20%3D2%285%29%2B5%2825%29)
![= 10+125](https://tex.z-dn.net/?f=%20%3D%2010%2B125)
![= 135](https://tex.z-dn.net/?f=%20%3D%20135)
Hence the answer is 135
1. A function can be represented verbally. For example, the circumference of a square is four times one of its sides.
2. A function can be represented algebraically. For example, 3x+6 3 x + 6.
3.A function can be represented numerically.
4. A function can be represented graphically.
I only found four, hopefully this helps.

Answer:
$189.75
Step-by-step explanation:
Whenever you want to find the percent of something, you need to turn the percent into a decimal. In this case, we need to find 115% of the wholesale price because there is a markup, so the cost will be higher.
115% as a decimal is 1.15. Here is how the equation will be set up:
$165 • 1.15 = $189.75
No rounding is necessary for this problem because it is already to the nearest cent.
