23.55 - 20.65 = 2.9
2.9 / 20.65 = 0.140436
0.140436 x 100 = 14.0436
Therefore that to the nearest tenth of a percent would be:
14% increase
Im using multiplication for this :p
Since small packages cost him $3.20 to send, and he has to sell 6 of them, i did the equation:
![3.20 * 6 = 19.20](https://tex.z-dn.net/?f=3.20%20%2A%206%20%3D%2019.20)
Now he has to send 4 large packages, each the price of $4.70. The equation:
If you want to add them both:
![18.80 + 19.20 = $38](https://tex.z-dn.net/?f=18.80%20%2B%2019.20%20%3D%20%2438)
<em>youre welcome :p</em>

Answer:
Please check the explanation!
Step-by-step explanation:
Given the equation
![f\left(x\right)=-2|x+1|-1](https://tex.z-dn.net/?f=f%5Cleft%28x%5Cright%29%3D-2%7Cx%2B1%7C-1)
As some of the absolute rules are:
NOW, let us solve!
Let us substitute all the table values
Putting x = -4
∵![\mathrm{Apply\:absolute\:rule}:\quad \left|a\right|=a,\:a\ge 0](https://tex.z-dn.net/?f=%5Cmathrm%7BApply%5C%3Aabsolute%5C%3Arule%7D%3A%5Cquad%20%5Cleft%7Ca%5Cright%7C%3Da%2C%5C%3Aa%5Cge%200)
![y=-6-1](https://tex.z-dn.net/?f=y%3D-6-1)
![y=-7](https://tex.z-dn.net/?f=y%3D-7)
So, when x = -4, then y = -7
Putting x = -3
![y=-2|-3+1|-1\:](https://tex.z-dn.net/?f=y%3D-2%7C-3%2B1%7C-1%5C%3A)
![y=-4-1](https://tex.z-dn.net/?f=y%3D-4-1)
![y=-5](https://tex.z-dn.net/?f=y%3D-5)
when x = -3, then y = -5
Putting x = -2
![y=-2\left|-2+1\right|-1](https://tex.z-dn.net/?f=y%3D-2%5Cleft%7C-2%2B1%5Cright%7C-1)
![y=-2-1](https://tex.z-dn.net/?f=y%3D-2-1)
![y=-3](https://tex.z-dn.net/?f=y%3D-3)
when x = -2, then y = -3
Putting x = -1
![y=-2\left|-1+1\right|-1](https://tex.z-dn.net/?f=y%3D-2%5Cleft%7C-1%2B1%5Cright%7C-1)
![y=-0-1](https://tex.z-dn.net/?f=y%3D-0-1)
![y=-1](https://tex.z-dn.net/?f=y%3D-1)
when x = -1, then y = -1
Putting x = 0
![y=-2\left|0+1\right|-1](https://tex.z-dn.net/?f=y%3D-2%5Cleft%7C0%2B1%5Cright%7C-1)
![y=-2-1](https://tex.z-dn.net/?f=y%3D-2-1)
![y=-3](https://tex.z-dn.net/?f=y%3D-3)
when x = 0, then y = -3
Putting x = 1
![y=-2\left|1+1\right|-1](https://tex.z-dn.net/?f=y%3D-2%5Cleft%7C1%2B1%5Cright%7C-1)
![y=-4-1](https://tex.z-dn.net/?f=y%3D-4-1)
![y=-5](https://tex.z-dn.net/?f=y%3D-5)
when x = 1, then y = -5
