Answer:

Approximately 18%

Step-by-step explanation:

1. Subtract the cost with tax by the cost without tax.

40-34=6

2. Create a proportion:

[tex]\frac{6}{34}[/tex]=[tex]\frac{x}{100}[/tex]

3. Cross Mutliply to get:

34x=600

4. Divide 34 by both sides to get

x=17.64...

The sales tax is approximately 18%
