The annual income of a restaurant in a shopping mall is about168,000. The effective passenger flow of the restaurant can reach about 26 people every day, and the consumption amount is about 70- 100 yuan. Here, let's calculate the consumption of 75 yuan per person. Then the turnover of one day is 2000 yuan, and the sales of one month is 60 thousand yuan. If the gross profit is calculated at 60% per month after removing the procurement cost and logistics cost, the gross profit per month is 36,000 yuan. Excluding the fixed cost of 22,000 yuan per month, the monthly net profit is 6.5438 yuan +0.4 million yuan, and the annual net profit is 6.5438 yuan +0.6 million yuan. To sum up, the annual profit of tea restaurants can reach 654.38 million.
