We will investigate how to determine a selling price of a product given at a discounted rate.

The original price ( O ) of the computer that Alex bought is:

$O\text{ = \$1200}$

The selling price of the computer is expressed as a fraction of the original price ( O ) as follows:

$S\text{ = }(5)/(6)\cdot O$

Using the above expression we will plug in the value of original price of the computer and solve for its selling price as follows:

$\begin{gathered} S\text{ = }(5)/(6)\cdot1200 \\ \\ S\text{ = \$1000} \end{gathered}$

Alex paid at the selling price ( S ) for the computer with a discount of ( D ) as follows:

$\text{Alex paid ( S = \$1000 ) with a discount of ( D = 1200 - 1000 = \$200 )}$
