Answer 1

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:

`\text{ Discounted price = Original Price x (}\frac{100\text{\% - \% Discount}}{100})`

We get,

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

Therefore, Sam paid $636 for the stereo.

The answer is letter B.
