Suppose the price of 60% profit is x yuan, then: x + 60% x = 64 & nbsp; & nbsp; & nbsp; & nbsp; 160% x = 64 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; X = 40, and the price of 20% loss is y yuan, then: y-20% y = 64 & nbsp; 80% y = 64 & nbsp; & nbsp; & nbsp; y = 80, so the total price is: 40 + 80 = 120 (yuan), the total price is: 64 + 64 = 128 (yuan) > the price, 128-120 = 8 (yuan) a: earned 8 yuan
