The discount is applied to the original sales price we'll call p. A discount of 30% means the price has dropped to 70% (100-30) of its original value, so 140=70p/100=7p/10. Therefore p=140*10/7=200 and the original sales price was $200. (The discount is 30% of this=$60 making 200-60 the purchase price after discount $140. What's not too clear is whether the three games each cost $140 or whether that was the total of all three games. Either way, the original price was $200.)
