The sale price is $3. 17%, or .75*$12 is $9. $9 is the amount of money that you save on the DVDs. So, you would do $12-$9 which would equal $3. You would end up paying $3 for the DVD. In this problem, $12 represents the original price of the DVD and $9 is the amount of money you save on the DVD. $3 is the amount of money you spend on the DVD. $3 is also the sale price of the DVD. In any type of these problems you do %* original price. This will give you the amount of money you save. You subtract the amount of money you save from the original price, and you will get the sale price which is what you will be paying for whatever is being represented in the problem. Hope I helped!
