Solution

For this case we know that the price is 10$ per bottle with 8% of tax

We can find the tax using this:

[tex]\frac{10}{100}=\frac{x}{8}[/tex]

With x= tax value, solving for x we got:

[tex]x=8\cdot\frac{10}{100}=0.8[/tex]

Then the total price is: 10+0.8 = 10.8

Then we can find the change like this:

20-10.8= 9.2
