問題詳情：

The workers could do nothing but turn to a German engineer for help, who drew a line on it and said, "Take off the part where the line is and change it or a new one." With a new line on, the machine began running well again. The engineer asked for $30,000 for what he had done. The following were what he wrote on a bill, "The new part only costs one dollar, and knowing where the problem with the machine costs $29,999."
