A store will sell a certain kind of clothing at a discount in the next season. If each clothing is sold at a 50% discount on the price, it will lose 20 yuan, and if it is sold at a 20% discount on the price, it will earn 40 yuan. How much is the price of each clothing? How much is the cost price of each clothing? How much discount can we get at most to ensure no loss? (use one yuan equation to solve)


Set the price of each garment as X
0.5X+20=0.8X-40
X = 200
The price of each dress is 200 yuan
