Accepted Answer
For this case we can make the following rule of three: 2.99 ----------> 100% x --------------> 7% From here, we clear the value of x. We have then: [tex]x = (7/100) * (2.99)
[/tex] Rewriting the expression we have: [tex]x = (0.07) * (2.99)
x = 0.2093 $[/tex] Answer: The sales taxes are: x = 0.2093 $
