How much is a fast food suitable for this problem, I say my personal opinion.

I am a hotel chef, engaged in this occupation for more than ten years, this is to be divided into you in a few cities, first take the first line of the city, say it, in Shenzhen, the price of a fast food is 30 yuan, obviously a little bit expensive, if in the second-tier cities or third-tier cities, a fast food is also more than ten dollars, the price of each city is not the same, my personal opinion, fast food this thing is some of the fried, the cost is not high, fast food pure profit of more than fifty percent, I think a fast food is the right money. The cost is not high, fast food pure profit of more than fifty percent, I think the price of a fast food is not more than 16 yuan is most appropriate.
