1. 20% off means it's 80% of the regular price so using a proportion, 80/100 = 1600/p 80p = 160000 p = 160000/80 = 2000
2. 1920$
3. Person above is correct. If you also need the inverse: (or do the reverse of formula below to also answer your original question) x = original value y = mark up percentage as a decimal z = new price x * (1 + y) = z e.g. $100 jacket is marked up 30% on the rack for you to buy it. Price on ticket = $130 = 100 * 1.30 = 130
