This is easy . There is a 20 percent discount which means now it’s only (100-20%) discount. This is 80% discount. Money saved is equal to 100-80% =20% And that 20% is equal to 13$ as per the passage. So now we need to calculate 1 percent of the item without discount . This is equal to 13/20 This is equal to .65 Now to find the original price you will need to multiply .65 to 100 this is equal to 65$.
