The original price of a dvd is $12. the sale price is 75% of the original price. find the sale price of the dvd

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!

The major difference is that a histogram is only used to plot the frequency of score occurrences in a continuous data set that has been divided into classes, called bins.  bar charts, on the other hand, can be used for a great deal of other types ofvariables  including  ordinal  andnominal  data sets.
