Astore advertises a 35% discount on a $951 computer system.

For this case we propose a rule of three:

$ 951 -------------> 100%

x -------------------> 35%

Where "x" is the variable that determines the amount of the discount equivalent to 35%.

Thus, the discount is $332.85.

The new price of the computer system is:

$951- $332.85 = $617.5

The new price of the computer system is: $617.5

3.76%
