这句话到底应该怎么翻译呢？

如果，您认为目前原料价格在100元上下的话，那么加工的直接成本就在1米1元以上。您就会认为我提的价格建议是合理的。

If, you think, the current price of raw material is about 100 Yuan, the cost of processing directly is over 1 Yuan per meter.
You will regard my price suggested reasonable.

If, in your opinion, the current 100 yuan in the price of raw materials from top to bottom, then the direct cost of processing in the 1 m above one yuan. You may think that I mentioned the price proposed is reasonable.
