Hualian Mall bought two products at the same time, each selling for 360 yuan, but one of them made a profit of 20%, and the other lost 20%. I would like to ask: Does Hualian Mall make a profit or a loss when it sells these two commodities? How much did you lose or earn?
华联商场同时买两件商品，每件都卖360元，但其中一件赚了20%，另一件亏了20%．请问：华联商场卖出这两件商品总的是赚了，还是亏了？亏或赚多少元？
