Round to the nearest whole percent.

Answer:  Percentage that Wednesday's sale price would be 80%of the original price for the pants.Step-by-step explanation:Let the original price of pants be 'x'.Discount rate on Tuesday = 15%Discount rate on Wednesday = 5%So, total discount rate = 15% +5% = 20%So, Amount of discount would be [tex]\dfrac{20}{100}\times x\\\\=0.20x[/tex]So, Price of pants on Wednesday becomes[tex]x-0.20x\\\\=0.8x[/tex]So, Percentage that Wednesday's sale price would be [tex]\dfrac{0.8x}{x}\times 100=80\%[/tex] of the original price for the pants.
