Explanation:

To find the total cost of the dvd we have to add the tax amount to the cost of the dvd without the tax.

Let's find the amount of the tax. We have to find 6% of $30:

[tex]30\times\frac{6}{100}=30\times0.06=1.8[/tex]

The amount of the tax is $1.80. Now we add it to the cost of the dvd without the tax:

[tex]30+1.80=31.80[/tex]

Answer:

The total cost of the dvd is $31.80
