You know that:
- The total is $212.00 and the sales tax is included.
- The bill without tax was $200.00.
Let be "x" the tax on her groceries (in dollars).
You need to subtract the bill without tax from the total amount of money Sandra paid for the groceries, in order to find the tax in dollars:
[tex]\begin{gathered} x=212-200 \\ x=12 \end{gathered}[/tex]To check it, you can multiply the total by 6%:
[tex]212\cdot\frac{6}{100}=12[/tex]Hence, the answer is: $12.00 (This is 6% of the total bill)
