First, the customer paid 65,438+000 yuan for the shoes. By the time she went to the temporary store to change money, Miss Wang was unprofitable, which was equivalent to the customer changing money. It turned out to be fake. If you lose 100 yuan, you lose 100 yuan.
Then, if the shoes are purchased in 45 yuan and discounted in 30 yuan, it means a loss 15 yuan.
Add them together and it is 1 15 yuan.
