If the bill was $52 and the tax rate is 6% then the total tax is equal to the 6% of $52. When we want to know the p% of a quantity Q we just need to multiply Q by p and divided by 100. Then the p% of Q is:
[tex]Q\cdot\frac{p}{100}[/tex]If we apply this to our problem we get:
[tex]tax=52\cdot\frac{6}{100}=52\cdot0.06=3.12[/tex]AnswerThen the answer is $3.12.
