Explanation / Answer

Regular price = $ 620

Sale Price = $ 530

a) Reg price - sale price = 620 -530 = $ 90

So, Regular price is [(90)/530 ]*100 = 16.98 = 17% more than regular price

b) Regular price is (620/530)*100 = 116.98 = 117 % of sale price

c) Sale price = (90/620)*100 = 14.51% = 14.5 % less than regular price

d) Sale Price = (530/530)*100 = 100% of sale price
