Given:

a.) Sam bought a stereo that was listed for $795.

b.) He saved 20% of the original cost by buying it at a sale and paying cash.

We will be using the following formula:

[tex]\text{ Discounted price = Original Price x (}\frac{100\text{\% - \% Discount}}{100})[/tex]

We get,

[tex]\text{ Discounted price = Original Price x (}\frac{100\text{\% - \% Discount}}{100})[/tex][tex]\text{= 795 x (}\frac{100\text{\% - 20\%}}{100})[/tex][tex]\text{ = 795 x (}\frac{80}{100})[/tex][tex]\text{ = 795 x 0.80}[/tex][tex]\text{ Discounted Price = \$}636.00[/tex]

Therefore, Sam paid $636 for the stereo.

The answer is letter B.
