18. Practical questions (30 19:1:19) Mechanical processing needs lubrication to reduce friction. An enterprise needs to process 90kg lubricating oil for a large-scale mechanical equipment, and the reuse rate of lubricating oil is 60%. According to this calculation, the actual oil consumption of processing a large-scale mechanical equipment is 36kg. In order to build a conservation oriented society and reduce oil consumption, a workshop of the enterprise organized personnel to tackle key problems to reduce the actual oil consumption, It not only reduces the lubricating oil consumption, but also improves the reuse rate of lubricating oil. It is found that on the basis of technological innovation, the reuse rate of lubricating oil consumption will increase by 1.6% for every 1kg reduction in lubricating oil consumption. In this way, the actual oil consumption of processing a large mechanical equipment will decrease to 12kg, How many kilos of lubricating oil is used for processing a large mechanical equipment? What is the reuse rate of lubricating oil?

20. Quadratic function, practical problems Zhenhua agency sells a kind of building material on behalf of a factory. When the selling price per ton is 260 yuan, the monthly sales volume is 45 tons. In order to improve the operating profit, the agency is prepared to reduce the price for promotion. According to the market survey, when the selling price per ton decreases by 10 yuan, the monthly sales volume will increase by 7.5 tons, A total of 100 yuan will be paid to the manufacturer and other expenses for each ton of building materials sold. Suppose the selling price of each ton of materials is x yuan, and the monthly profit of the distributor is y yuan (1) Find the functional relationship between Y and X (it is not required to write the value range of x) (2) When the selling price is set at RMB per ton, what is the maximum monthly profit of the store?
