Well if the pen's original price is $20 and it has been marked down to $12. There is a difference of $8, right? That is the discount in dollars, but to find the percent, what is $8 of $20? For this we can use simple fractions.

8/20 (Assume that the $20 is 100%, with no discounts. The $8 is the discount out of 
         100%)

8/20 = ??/100

The ?? should be 40. So this means the $8 is 40% out of the total ($20 which is 100%)
