When we know the tax rate of an article (tax%) we can calculate the costs by taxes of that article like this:


\text{tax}=priceofthearticle*\frac{\text{tax\%}}{100}

In this case, the price of our article is $511.95 and the tax rate is 7.25%, replacing in the formula above we find the cost associated with the tax, like this:


\text{tax}=511.95*(7.25)/(100)\approx37.12

And the total cost, would be the sum of the listed price and the tax cost:


\text{total cost}\approx\text{37.12+511.95}\approx\text{549.07}

Then, the total cost is $549.07
