The table below shows a business plan to put items on sale. Shown are the original price and the sale price of a list of items. Calculate the percent change of all the items to the nearest percent and put these numbers in the empty percent change locations in the table. Calculate the percent sale numbers (% Sale = 100 − % Change). Then plot a graph of these data, placing the original price on the horizontal axis and the percent sale on the vertical axis.
