Hello there!
![4v - 1 = -5v - 10](https://tex.z-dn.net/?f=4v%20-%201%20%3D%20-5v%20-%2010)
Explanation:

First you had to add by 1 from both sides of the equation.
![4v-1+1=-5v-10+1](https://tex.z-dn.net/?f=4v-1%2B1%3D-5v-10%2B1)
Simplify
![4v=-5v-9](https://tex.z-dn.net/?f=4v%3D-5v-9)
Then you add by 5v from both sides of the equation.
![4v+5v=-5v-9+5v](https://tex.z-dn.net/?f=4v%2B5v%3D-5v-9%2B5v)
Simplify
![9v=-9](https://tex.z-dn.net/?f=9v%3D-9)
Divide by 9 from both sides of the equation.
![\frac{9v}{9}=\frac{-9}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B9v%7D%7B9%7D%3D%5Cfrac%7B-9%7D%7B9%7D)
Simplify it should be the correct answer.

0.02*x+0.7*8=0.67(x+8)
0.02x+5.6=0.67x+0.67*8
0.02x+5.6=0.67x+5.36
0.67x-0.02x=5.6-5.36
0.65x=0.24
x=0.369 gallons
I think it’s 1.75 sorry if this is wrong
Hey! To do this, first we need to find our sale price. To do this. take the $80 and multiply it by 180% (1.8) because of the 80% markup and you get $144. Now, you need to find the commission. Take the $144 and multiply it by the 14% commission to get $20.16. Hope this helped!
