请帮我解决一个数学问题~（英语）

Your business buys 36,500 litres of calcium sulphate each year. You could order it all at once, but then you would need to rent storage space for it, and that costs $1 per litre. You could, every day, put in an order for 100 litres—that would reduce your storage costs to $100, but every time you put in an order you have to pay a $14.60 processing fee. How often should you order, and how much, to minimize the total of your ordering and storage costs?

您的企业每年购买3.65万升硫酸钙。你可以一下子订购它，但您将需要为它们租用存储空间，而且售价为每公升1美元。你可以每天购买100升，这样一来可以减少储存成本100元，但你每次必须支付14.60美元手续费。应该怎么来订货，每次多少，才能尽量减少您的订购和储存费用总额？
